The awesome-gee-community-datasets are community-sourced geospatial datasets made available for use by the larger Google Earth Engine community and shared publicly as Earth Engine assets. The project was started with the idea that a lot of research datasets are often unavailable for direct use and require preprocessing before use. This catalog lives and serves alongside the [Google Earth Engine data catalog](https://developers.google.com/earth-engine/datasets/catalog) and also houses datasets that are often requested by the community and under a variety of open license.
You can read about the history and more in the [Medium Post article here](https://medium.com/geospatial-processing-at-scale/community-datasets-data-commons-in-google-earth-engine-8585d8baef1f)

# Why donate to the Community Catalog
[](https://github.com/sponsors/samapriya)
The **GEE Community Catalog** is an Open Source and unfunded project that is developed and maintained by a one person team. You can read me and the work further in the [about me section](https:/gee-community-catalog.org/aboutme). While I started this as a personal side project in 2020, the realization was always present that this project has far reaching implications and applications in the larger geospatial community. I realized that this project could benefit not just the research community who are often producing valuable research products from their research but users who are interested in a share collection of community sources data sources. Behind the scenes most community catalog requests for adding a dataset to the community catalog is triaged by me, evaluated based on multiple factors such as license, data size and preprocessing complexity before I start the work on getting it ready.
The **Insiders program** is designed for those who are helping keep open source projects sustainable and support the growth and curation of the catalog. As such this program is for sponsors and data contributors to the project you can sponsor the project by clicking on the sponsor button above ☝ or submit a [new dataset or tutorial request](https://gee-community-catalog.org/contributing/). If you fit under any of those categories fill this form to [get insiders access](https://web.archive.org/web/20240416082114/https://forms.gle/VPmETGKyvMAd37MV6). As an Insider, you'll be added to the "catalog-contributors" Google Group, giving you early access to datasets as they are processed, reviewed, and even those not yet released. You'll also receive occasional changelog and update emails, and have the ability to post questions, concerns, and thoughts to the group. And if we meet ask me for stickers to help spread the word 😊.
Over the last 4 years the project backend now includes over 100,000+ lines of code to often preprocess the dataset or make it ingest ready for Google Earth Engine and making it available for the geospatial community of GEE users. Currently the site serves over 500,000 requests from over 160+ countries. This work is built around creating a **Community Data Commons** and if you can and wish to support and donate to the project which goes towards simple things like cost of hosting, preprocessing feel free to do so using Github Sponsorship Tier setup for this project.

The Awesome GEE (Google Earth Engine) Community Catalog is a valuable resource for researchers, developers, and environmental scientists. It organizes a diverse range of geospatial datasets into thematic groups, making them more accessible and findable. This structured approach allows users to efficiently locate datasets pertinent to their specific fields of study or interest.
!!! tip "Insiders Program and Insiders only datasets"
**Some datasets are part of the Insiders only datasets and they [can be found here](https://gee-community-catalog.org/insiders). The insiders program is designed for those who are helping keep open source projects sustainable and support the growth and curation of the catalog. The Insiders Program grants access to a few special selection of datasets. You can be part of the program click on the link :point_up: to find out more.**
#### Thematic Groups
The datasets in the Awesome GEE Community Catalog are categorized into several thematic groups, for example:
* Population and Socioeconomic Datasets: These datasets provide crucial information on demographics, economic activities, and social indicators, which are essential for urban planning, public health, and socio-economic research.
* Hydrology Datasets: This category includes data on water bodies, hydrological cycles, and water quality, supporting research and decision-making in water resource management, flood risk assessment, and environmental conservation.
* Global Land Use and Land Cover Datasets: These datasets offer insights into land use patterns and changes in land cover over time, aiding studies in agriculture, forestry, urbanization, and climate change.
* Climate and Weather Datasets: Essential for climate science, these datasets include historical and real-time data on weather patterns, temperature, precipitation, and other climatic factors.
???+ note
**While every effort has been made to place datasets in the most suitable thematic groups, it is acknowledged that some datasets may rightfully belong to more than one category. Users are encouraged to explore multiple themes if their research spans across different areas.**
#### Accessibility and Findability
The thematic grouping of datasets in the Awesome GEE Community Catalog enhances their accessibility and findability. By organizing datasets into clearly defined categories, the catalog simplifies the process of searching and identifying relevant data. This organization not only saves time but also ensures that users can easily locate the most appropriate datasets for their specific needs with the changelog recording periodic updates.

### Search Features Index (`docs/search_features/index.md`)
# Catalog Assistant
The **Catalog Assistant** is a custom-designed assistant for the Community Catalog, available at [search.gee-community-catalog.org](https://search.gee-community-catalog.org). Ask it questions in plain language and it returns summaries **grounded** in the catalog's own pages and dataset metadata — with links back to the source material, so you can verify every answer. You can still use the embedded search within the Community Catalog for basic keyword or text-match lookups.
[Open the Catalog Assistant here.](https://search.gee-community-catalog.org)
???+ note
**If the assistant doesn't work as expected, try disabling any widget blocker extensions or using an incognito window to troubleshoot.**
## Salient Features
- Answers are **grounded** in the catalog — every summary links back to the source pages and dataset metadata, boosting trust and minimizing inaccuracies.
- Supports **multiple languages** — ask in your preferred language and the results are summarized in the same language.
- As with all generative assistants, **prompt formulation** matters. Slight changes in phrasing can often yield better results.
## Limitations
- Summaries are generated from a limited set of top results, so not every matching dataset may appear in a given answer.
- Summaries may evolve over time as the **context window** changes, so your answer might vary between searches.
## Previous deployment
Earlier versions of the assistant ran as a **Vertex AI** search widget built on **RAG (Retrieval Augmented Generation)**, drawing on two data stores — the Community Catalog pages and a JSON data store — to keep its summaries grounded in reliable sources. That deployment was offered in **Beta** while we tested and refined it, and its output was a server-side–controlled widget that generated summaries from up to ten search results. Learn more about RAG in [this earlier blog post](https://datacommons.substack.com/p/can-ai-turn-slides-into-podcasts). Notable changes from that phase:
- Added a secondary data store (JSON) to speed up parsing of details like licenses and links.
- Introduced a "Back to the Community Catalog" button for easy navigation back to the main catalog.
- Implemented custom system instructions to improve output quality and relevance.

### Tutorials Index (`docs/tutorials/index.md`)
# Community Catalog Tutorials
In this section of the community catalog, we'll explore user contributed Tutorials featuring catalog datasets or a mix of community catalog and the main catalog.
#### The Importance of Tutorials
Tutorials are an essential component of any learning platform, as they provide a clear and concise guide on how to achieve specific goals or solve particular problems. In the context of Earth Engine, tutorials are particularly valuable because they help users:
* Understand the capabilities and limitations of EE's tools and datasets
* Learn how to manipulate and analyze data using EE's API and visualizations
* Apply EE's resources to real-world problems and scenarios
#### Community Catalog Tutorials: A Valuable Resource
The Community Catalog tutorials are designed to be a comprehensive resource for learning about Earth Engine. These tutorials cover a range of topics, including:
* Data discovery and manipulation
* Visualization and analysis techniques
* Integration with other tools and platforms
* Best practices for working with EE's datasets
These tutorials are not only helpful for beginners but also serve as a valuable reference for experienced users looking to expand their skills or explore new applications.
#### Encouraging Participation: Contributing Code Examples, Tutorials, Edits, and More!
We encourage participation in our releases by contributing code examples, tutorials, edits through pull requests, documentation, or by being involved in planning and developing the community catalog further. Your contributions ensure that you are recognized as part of the citation for each release.
#### Benefits of Contributing

### About Us (`docs/about_us.md`)
# About Us
[](https://jetstream-cloud.org/)
[](https://doi.org/10.5281/zenodo.12057445)
[](https://github.com/sponsors/samapriya)
Welcome to the Awesome GEE Community Catalog — a home for discovering and contributing geospatial datasets built for use with Google Earth Engine. It's an **unfunded, open-source, grassroots project** with a single mission: to collect **community-sourced** and **community-generated** geospatial data and make it **accessible** and analysis-ready, fostering collaboration and reducing the digital divide.
The catalog was created and is maintained by [Dr. Samapriya Roy](https://www.linkedin.com/in/samapriya/) — still very much a one-person team. He is a [Google Developer Expert for Google Earth Engine](https://g.dev/samapriya) and the founder and CEO of [Spatial Bytes](https://spatialbytes.work/), a geospatial and Geo AI consultancy, as well as a Research Scientist and Senior Geospatial Engineer at the [Desert Research Institute](https://www.dri.edu/) and an advisor to NSF's NEON. Earlier in his career he was a Senior Product Manager at MAXAR and worked at Planet Labs. Dr. Roy holds a Ph.D. in Geography from Indiana University Bloomington and brings geospatial expertise as affiliate faculty at the University of Hawaiʻi at Mānoa and a Designated Campus Colleague at the University of Arizona. A prolific [open-source developer](https://github.com/samapriya), he builds tools that make Earth observation data easier to find, access, and use — and champions open data and the idea of a geospatial commons that this catalog embodies.
The catalog is shaped by the community itself — through data requests, tutorial contributions, and the input, advice, and feedback of the **#awesome** community that uses it every day. It thrives on community participation and open-source principles, giving researchers, developers, and enthusiasts high-quality, analysis-ready data to build on. This year, the [National Science Foundation (NSF) ACCESS program](https://access-ci.org/) granted us 1.5 million Service Units (CPU core-hours) to continue this work through [**Jetstream2, an NSF project**](https://jetstream-cloud.org/), which lets us preprocess datasets as requests come in.
## Community Contributions
Our catalog is powered by the contributions of the GEE user base. Community members submit datasets, which are then reviewed, usually downloaded and preprocessed into Earth Engine–ready form, and finally added to the catalog for everyone to use. This collaborative approach keeps the collection diverse and rich — spanning topics from waterbodies and population distribution to drought monitoring and beyond. Every contribution expands the repository and makes it a stronger go-to resource for geospatial data. 🔍
## Update Schedule
We know how much reliable, current data matters. Some datasets refresh on a fixed cadence; others follow a more ad hoc schedule, updated as requests come in or as new information about a dataset becomes available. This flexibility lets us respond to the community's needs while keeping the data relevant and accurate. 🗓️
**We rely on the community to spread the word and share the catalog with others. Please cite and attribute the catalog [using our citation](http://gee-community-catalog.org/reference/) — it makes the project more visible and helps it grow.**

### Code Of Conduct (`docs/code_of_conduct.md`)
# Code of Conduct
The awesome-gee-community-catalog consists of community-sourced geospatial datasets made available for use by the larger Google Earth Engine community and shared publicly as Earth Engine assets. The project was started with the idea that many research datasets are often unavailable for direct use and require preprocessing beforehand. This catalog lives and serves alongside the [Google Earth Engine data catalog](https://developers.google.com/earth-engine/datasets/catalog) and also houses datasets that are frequently requested by the community, under a variety of open licenses.
You can read about the history and how this project started in the [Medium Post article here](https://medium.com/geospatial-processing-at-scale/community-datasets-data-commons-in-google-earth-engine-8585d8baef1f)
Community Datasets added by users and made available for use at large.

### History (`docs/history.md`)
# Building Data Commons
**Communities are what communities build together.** Google Earth Engine (GEE) is powerful not only because of what it can compute, but because of who gathers around it — a community that iterates in the open, shares its code, and learns in public. The Awesome GEE Community Catalog began as an attempt to give that spirit a home for *data*: a place where anyone could contribute a dataset and everyone could find one.
## How it started
The catalog started with a single question. A user asked where to find Facebook's high-resolution population density maps — a dataset the official GEE catalog didn't carry. Hosted by Columbia University and resolving population down to 30 meters, it was exactly the kind of valuable, hard-to-reach layer that fell through the cracks. Rather than treat that gap as a dead end, we treated it as an experiment: what if the community itself maintained the datasets it needed?
That Facebook dataset became the first entry in the catalog — and, fittingly, one of its most frequently updated. The full origin story is captured in the foundational [blog post](https://samapriyaroy.medium.com/community-datasets-in-google-earth-engine-an-experiment-b72daa474819).
## The guiding principle
The catalog is built on an old idea about shared resources. Elinor Ostrom's Nobel-winning work on the governance of commons showed that communities can steward shared resources sustainably when they agree on the norms for using them — the same principle that carried open-source projects like Linux and collaborative knowledge bases like Wikipedia. What works for a physical commons, we believed, could work for a digital one.
So we set out to build a **Community Data Commons**: the **Awesome GEE Community Catalog**.
## Why it matters
Earth Engine democratized access to planetary-scale *processing*. The catalog aims to do the same for the *data* — lowering the barrier to a growing, curated collection of public datasets so that finding the right layer is no longer the hard part of a project.
The real challenge, and the reason a commons model fits, is scale in both directions: the catalog has to serve continental datasets and one-off community contributions with equal care. It works because the Earth Engine ecosystem already runs on learning, adaptation, and iteration. The catalog simply gives that culture a shared shelf — a bridge between the people who publish data and the people who need it.
It is, and will remain, a collaborative effort. Its continued growth depends on the community that builds it. **[Contribute a dataset](contributing/submit.md)** and help the commons grow.

### Projects GPWv4 (`docs/projects/GPWv4.md`)
# Gridded Population of the World Version 4 Administrative Unit Center Points with Population Estimates
The Gridded Population of the World, Version 4 (GPWv4): Administrative Unit Center Points with Population Estimates, Revision 11 consists of UN WPP-adjusted population estimates and densities for the years 2000, 2005, 2010, 2015 and 2020, as well as the basic demographic characteristics (age and sex) for the year 2010. The data set also includes administrative name, land and water area, and data context by administrative unit center point (centroid) location. The center points are based on approximately 13.5 million input administrative units used in GPWv4, therefore, these files require hardware and software that can read large amounts of data into memory.
Purpose:
To provide a vector (point) version of the input administrative units used in GPWv4 with population estimates, densities, 2010 basic demographic characteristics, and administrative name, area, and data context for use in data integration.
The documentation for this data set is available [here](http://sedac.ciesin.columbia.edu/data/set/gpw-v4-admin-unit-center-points-population-estimates-rev11/docs)

### Projects S2TSLULC (`docs/projects/S2TSLULC.md`)
# ESRI 10m Annual Land Cover (2017-2025)
Time series of annual global maps of land use and land cover (LULC) was updated to v3 with global 10m land cover from 2017-2024. The maps are derived from ESA Sentinel-2 imagery at 10m resolution. Each map is a composite of LULC predictions for 9 classes throughout the year in order to generate a representative snapshot of each year. This dataset was generated by Impact Observatory, who used billions of human-labeled pixels (curated by the National Geographic Society) to train a deep learning model for land classification. The global map was produced by applying this model to the Sentinel-2 annual scene collections on the Planetary Computer. Each of the maps has an assessed average accuracy of over 75%. These datasets produced by Impact Observatory and licensed by Esri were fetched from [Impact Observatory](https://api.impactobservatory.com/stac-aws/collections/io-10m-annual-lulc/items)
This map uses an updated model from the 10-class model and combines Grass(formerly class 3) and Scrub (formerly class 6) into a single Rangeland class (class 11). The original Esri 2020 Land Cover collection uses 10 classes (Grass and Scrub separate) and an older version of the underlying deep learning model. The [Esri 2020 Land Cover map was also produced by Impact Observatory and you can find it in GEE here](https://samapriya.github.io/awesome-gee-community-datasets/projects/esrilc2020/). The map remains available for use in existing applications. New applications should use the updated version of 2020 once it is available in this collection, especially when using data from multiple years of this time series, to ensure consistent classification.

9. Snow/Ice
Large homogeneous areas of permanent snow or ice, typically only in mountain areas or highest latitudes; examples: glaciers, permanent snowpack, snow fields.
10. Clouds
No land cover information due to persistent cloud cover.
11. Rangeland
Open areas covered in homogeneous grasses with little to no taller vegetation; wild cereals and grasses with no obvious human plotting (i.e., not a plotted field); examples: natural meadows and fields with sparse to no tree cover, open savanna with few to no trees, parks/golf courses/lawns, pastures. Mix of small clusters of plants or single plants dispersed on a landscape that shows exposed soil or rock; scrub-filled clearings within dense forests that are clearly not taller than trees; examples: moderate to sparse cover of bushes, shrubs and tufts of grass, savannas with very sparse grasses, trees or other plants.

### Projects Aces Bhutan (`docs/projects/aces_bhutan.md`)
# ACES-Enhanced Rice Crop Maps for Bhutan (2016-2022)
Annual crop type rice maps for 2016-2022 for enabling improved food security decision making has remained a challenge in Bhutan. These maps were developed in collaboration with the Bhutan Department of Agriculture and SERVIR. Through focusing on advancing Science, Technology, Engineering, and Mathematics (STEM) in Bhutan, an effort to co-develop a geospatial application known as the [Agricultural Classification and Estimation Service (ACES)](https://github.com/SERVIR/ag-classification-estimation/tree/main) was created. This dataset and paper focuses on the co-development of an Earth observation informed climate smart crop type framework which incorporates both modeling and training sample collection. The [ACES web application](https://servirglobalnet.users.earthengine.app/view/aces-bhutan) and subsequent ACES modeling software package enables stakeholders to more readily use Earth observation into their decision making process. Additionally, this data set and paper offers a transparent and replicable approach for addressing and combating remote sensing limitations due to topography and cloud cover, a common problem in Bhutan. Lastly, this approach resulted in a Random Forest "LTE 555" model, from a set of 3,600 possible models, with an overall test Accuracy of 85% and F-1 Score of .88 for 2020. The model was independently validated resulting in an independent accuracy of 83% and F-1 Score of .45 for 2020.

### Projects Af Cmask (`docs/projects/af_cmask.md`)
# Ensemble Source Africa Cropland Mask 2016
In order to produce the most accurate cropland layer at 30 m spatial resolution for Africa, the cropland layers extracted from four remote sensing land cover datasets were integrated. The four datasets covered the period 2015 to 2017. Hence, the constructed cropland layer was produced for the nominal year 2016. To build the final layer, the cropland mapping accuracies of the four cropland layers were firstly investigated at the units of Agro-ecological zones. Then, the best cropland layers for all zones were spatially joined. The resulted cropland layer is a binary mask with higher overall accuracy than individual layers and more consistent with FAO official statistics.

### Projects Af Trees (`docs/projects/af_trees.md`)
# High resolution map of African tree cover
This dataset leverages high-resolution satellite imagery obtained from a nano-satellite constellation, accessible in the tropics through Norway's International Climate and Forest Initiative (NICFI) programme. The primary goal of this dataset is to comprehensively map both forest and non-forest trees on a continental scale across Africa, surpassing the precision of previous endeavors in mapping woody vegetation at large scales.
Utilizing a machine learning approach, we employ 3 m PlanetScope satellite imagery to segment tree canopy cover across Africa, reaching the level of individual scattered trees. The dataset provides a detailed quantification of the contribution of trees located outside traditional forested areas to the overall tree cover within each country. Notably, at the continental scale, our analysis reveals that 29% of the total tree cover exists outside regions classified as forests in a contemporary state-of-the-art map based on Sentinel-2 10 m imagery.

### Projects Agera5 Datasets (`docs/projects/agera5_datasets.md`)
# AgERA5 (ECMWF) dataset, version 2.0
Daily surface meteorological data for the period from 1979 to present as input for agriculture and agro-ecological studies. This dataset is based on
the hourly ECMWF ERA5 data at surface level and is referred to as AgERA5, version 2.0. Acquisition and pre-processing of the original ERA5 data is a complex and
specialized job. By providing the AgERA5 dataset, users are freed from this work and can directly start with meaningful input for their analyses and
modeling. To this end, the variables provided in this dataset match the input needs of most agriculture and agro-ecological models. Data were
aggregated to daily time steps at the local time zone and corrected towards a finer topography at a 0.1° spatial resolution. The correction to the 0.
1° grid was realized by applying grid and variable-specific regression equations to the ERA5 dataset interpolated at 0.1° grid. The equations were
trained on ECMWF's operational high-resolution atmospheric model (HRES) at a 0.1° resolution. This way the data are tuned to the finer topography,
finer land use pattern, and finer land-sea delineation of the ECMWF HRES model. You can find [additional information here](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-agrometeorological-indicators?tab=overview) and [in the climate engine org dataset page here](https://support.climateengine.org/article/58-era5-ag)

### Projects Ai0 (`docs/projects/ai0.md`)
# Global Aridity Index
The Global Aridity Index (Global-Aridity_ET0) and Global Reference Evapotranspiration (Global-ET0) Version 3 dataset provides high-resolution (30 arc-seconds) global raster climate data for the 1970-2000 period, related to evapotranspiration processes and rainfall deficit for potential vegetative growth, based upon the implementation of a Penman Monteith Evapotranspiration equation for reference crop. The dataset follows the development and is based upon the [WorldClim 2.1](https://www.worldclim.org/data/worldclim21.html) at 30 arc seconds or ~ 1km at the equator. You can read the [paper here](https://www.nature.com/articles/s41597-022-01493-1)
Aridity Index represent the ratio between precipitation and ET0, thus rainfall over vegetation water demand (aggregated on annual basis). Under this formulation, Aridity Index values increase for more humid conditions, and decrease with more arid conditions. The Aridity Index values reported within the Global Aridity Index_ET0 geodataset have been multiplied by a factor of 10,000 to derive and distribute the data as integers (with 4 decimal accuracy). This multiplier has been used to increase the precision of the variable values without using decimals.

### Projects Airtemp (`docs/projects/airtemp.md`)
# Global Daily near-surface air temperature
Near-surface air temperature (Ta) is a key variable in global climate studies. A global gridded dataset of daily maximum and minimum Ta (Tmax and Tmin) is particularly valuable and critically needed in the scientific and policy communities. Zhang et al. (2022) developed a global dataset of daily Tmax and Tmin at 1-km resolution over land (50° S–79° N) through the combined use of station-based ground Ta measurements and satellite observations (i.e., digital elevation model, and land surface temperature) via a state-of-the-art statistical method named Spatially Varying Coefficient Models with Sign Preservation (SVCM-SP). The published dataset covered 2003–2020 and has since been extended, so the collection now spans **2003 to 2024**.
This gridded 1 km resolution global (50° S ~ 79° N) daily maximum and minimum near-surface air temperature dataset (2003–2024) was generated using a seamless 1 km resolution land surface temperature dataset, a 30-arc second (~1 km) resolution digital elevation model (DEM) data, and air temperature observations at weather stations and a spatially varying coefficient model with sign preservation (SVCM-SP) algorithm. The gridded air temperature dataset is of great use in global studies of urban, climate, and hydrology.
Reported accuracies from the 10-fold cross-validation in the source publication give root mean square errors ranging from 1.20 to 2.44 °C for Tmax and 1.69 to 2.39 °C for Tmin, with accuracy affected primarily by land cover type, elevation range, and climate background.

Disclaimer: Whole or parts of the dataset description were provided by the author(s) or their works.
#### Data preprocessing
The datasets were generated regionally and for tmax and tmin. The tmax and tmin were combined into a single collection for the regions generated. Additional metadata called "prop_type" was added to allow for filtering along with other metadata like the day of year and the actual date information for date based filtering. The source data are distributed as GeoTIFFs in the MODIS ellipse sinusoidal projection at 1 km, with temperature stored in units of 0.1 °C; the datasets were projected to EPSG 4326 before being ingested to Google Earth Engine.

### Projects Amazon Peat (`docs/projects/amazon_peat.md`)
# Amazonian Peatland Extent
Tropical peatlands represent some of the most carbon-dense terrestrial ecosystems on the planet, playing a significant role in the global carbon cycle. However, substantial uncertainty exists in estimating their global extent and carbon storage potential. This dataset provides the first field-data-driven model of peatland distribution across the Amazon basin, developed using 2,413 ground reference points and a random forest model applied to a combination of remote sensing products.
The model predicts an Amazonian peatland extent of approximately 251,015 km² (95th percentile confidence interval: 128,671–373,359 km²), which is larger than that of the Congo Basin but 30% smaller than other recent model-based estimates. The dataset addresses key spatial gaps in ground reference data, particularly in regions like Brazil and Bolivia, where uncertainty remains high. The model highlights peatland areas with varying degrees of confidence, such as northern Peru, the Rio Negro basin, and Bolivia, providing a critical resource for future research and field validation efforts. You can read the paper [here](https://iopscience.iop.org/article/10.1088/1748-9326/ad677b/pdf) and download the [datasets here](https://zenodo.org/records/13142590)
**Data Highlights**
* Model Type: Random forest-based prediction using field reference points and remote sensing data.
* Spatial Extent: Amazon basin, including northern Peru, Rio Negro basin, southwestern Orinoco basin, and Bolivia.
* Predicted Peatland Extent: 251,015 km² (95% CI: 128,671–373,359 km²).
* Model Performance: High confidence in certain areas like northern Peru; higher uncertainty in regions like Brazil, Bolivia, and the Rio Negro basin.
* Field Reference Points: 2,413 ground points in and around Amazonian peatlands.
* Predicted extent of Peat (organic soil of ≥ 30 cm thickness) across the study area (Amazon basin below 500 m and mean annual precipitation >1,390 mm) at 90 m resolution.

### Projects Annual Nlcd (`docs/projects/annual_nlcd.md`)
# Annual NLCD Land Cover Dataset
The USGS Land Cover program integrates methodologies from the National Land Cover Database (NLCD) and the Land Change Monitoring, Assessment, and Projection (LCMAP), along with advanced deep learning, to create Annual NLCD a dataset suite that includes six products, each representing various U.S. land cover and change characteristics. The U.S. Geological Survey’s (USGS) Annual NLCD Collection 1.0 leverages innovations from the National Land Cover Database (NLCD) and Land Change Monitoring, Assessment, and Projection (LCMAP) projects, incorporating modern deep learning techniques to deliver accurate, annual land cover and surface change data across the U.S.
Since 1985, Annual NLCD provides six products covering land cover, change, confidence, impervious surfaces, and spectral changes based on Landsat data, facilitating resource management and decision-making.These products leverage Landsat satellite data and are intended for applications in science, resource management, and decision-making, spanning from 1985 to 2024. This dataset supports various environmental analyses, such as urban growth studies, wetland monitoring, agricultural management, and climate impact assessments. Its annual updates and classification confidence features provide essential insights for long-term land use planning and change detection. You can acces [User Guide here](https://www.mrlc.gov/sites/default/files/docs/LSDS-2103%20Annual%20National%20Land%20Cover%20Database%20(NLCD)%20Collection%201%20Science%20Product%20User%20Guide%20-v1.0%202024_10_15.pdf)
#### Dataset Products and Descriptions
- **Land Cover**: A sixteen-class system based on the modified Anderson Level II classification, categorizing dominant surface types like water, forests, and urban areas per pixel. RGB values visually differentiate these categories, ensuring compatibility across federal systems.
- **Land Cover Change**: Tracks annual land cover shifts by comparing consecutive years, using concatenated codes (e.g., 9590 for wetland transitions) to identify changes. Areas without change retain their classification.
- **Land Cover Confidence**: Provides confidence scores based on deep learning probabilities, indicating the model’s certainty in class assignments. Scores are uncalibrated but gauge classification reliability.
- **Fractional Impervious Surface**: Measures the percentage of impermeable surfaces (0-100%) within a 30-meter pixel, informing developed area classifications like urban or suburban based on defined thresholds.
- **Impervious Descriptor**: Differentiates urban, non-urban, and road surfaces within developed areas, offering a clear map of roads distinct from other urban features for detailed analysis.
- **Spectral Change Day of Year**: Identifies the day significant spectral changes occur (values 1-366), pinpointing disturbances (e.g., fires) beyond seasonal variations, enabling temporal change tracking.

### Projects Aogcm Cmip6 (`docs/projects/aogcm_cmip6.md`)
# Current and projected climate data for North America (CMIP6 scenarios)
Atmosphere-Ocean General Circulation Model (AOGCM) were developed to simulate climate variability on a wide range of time scales and are often tested in coupled simulations and data assimilation mode. You can [read more about AOGCMs and CMIP6 here](https://www.carbonbrief.org/cmip6-the-next-generation-of-climate-models-explained). The datasets on this page have been developed by AdaptWest, a project funded by the Wilburforce Foundation to develop information resources for climate adaptation planning. The data were generated using the ClimateNA software. ClimateNA uses data from PRISM and WorldClim for current climate, and downscales data from the Coupled Model Intercomparison Project phase 6 (CMIP6) database corresponding to the 6th IPCC Assessment Report for future projections.
Ensemble projections are average projections from 8 CMIP5 models (table below) that were chosen to represent all major clusters of similar AOGCMs. In addition to the ensemble projections, data are also provided from 9 individual AOGCMs (table below) that are representative of the larger ensemble. Nine individual models were selected to represent all major clusters of similar AOGCMs. A broader set of 8 AOGCMs were used to create the ensemble data. Ensemble projections are also provided here for a greater range of time periods and scenarios than are the projections from individual AOGCMs.

* All of the 9 individual AOGCM models are added to the collection pertaining to each climate variable and named Climate-Models_(Variable Name). The ensemble models are ingested as along with the climate normals.
* Both AOGCM ensemble and individual models have date range and emission scenario type **emission_scenario** and **start** and **end** dates are added as property.
* Since the Climate-Models-(Variable Name) collection consists of 9 individual models another metadata field is added to those collections namely **model** to filter by model name.
* Since all Climate variables are monthly , an extra metadata called **month** is added to the climate normals, ensemble and the individual model collections for further slicing the data as needed.
* Version number for model and period for 20 year and 30 year monthly variables are now included in the metadata.

#### Approach used to compute the Landsat-derived forest age for Canada (2019)
Map for displaying the approach followed to compute forest age for the treed areas in Canada’s forested ecosystems for a given year, in this case 2019.
1. The disturbance approach uses change detection protocols to detect disturbance from 1985 to 2019, with time since disturbance used as a proxy for forest age.
2. The recovery approach uses Landsat surface reflectance composites to identify pixels exhibiting evidence of recovery from a disturbance that occurred within the twenty years prior to 1985, allowing for the extension of forest age estimates to 1965. Finally,
3. The allometric approach couples inverted allometric equations with maps of forest structure and productivity metrics to model forest age for those pixels that show no evidence of disturbance or recovery to a maximum mapped age of 150 years.
Forest area codes:
0: Non treed
1: Disturbance approach
2: Recovery approach
3: Allometric approach

### Projects Ca Fao (`docs/projects/ca_fao.md`)
# Canada Landsat derived FAO forest identification (2019)
Landsat-based forest area consistent with FAO definitions for Canada's forested ecosystems. To conform with international reporting guidelines and programs, using Landsat data we map the forest area for Canada following the Food and Agricultural Organization of the United Nations (FAO) definition. The FAO definition incorporates land use, whereby trees removed by fire and harvesting for instance, remain forest as the trees will return. Annually representative maps were produced using over three decades of annual land cover data generated from Landsat derived time series land cover and change information (to generate a spatially explicit estimate of the forest area of Canada in 2019). We mapped the area of 'forest', as defined by the FAO, for Canada's 650 Mha of forested ecozones. The map includes the current forest cover in a given year (i.e. 2019), plus the satellite-based temporally informed forest area where tree cover had been temporarily lost due to fire or harvest. See [Wulder et al. (2020)](https://doi.org/10.1093/forestry/cpaa006) for an overview of the methods, data, image processing, as well as information on accuracy assessment using Canada’s National Inventory (NFI). You can [download the dataset here](https://opendata.nfis.org/downloads/forest_change/CA_FAO_forest_2019.zip)

### Projects Ca Fires (`docs/projects/ca_fires.md`)
# Canada 2023 Wildfires
Canada's 2023 wildfire season represented the largest area burned in a single fire season in Canada’s modern history. Using the Tracking Intra- and
Inter-year Change (TIIC) algorithm, wildfires occurring within Canada’s forested ecosystems during the 2023 fire season were detected at a 30-m
resolution. Time series data used to identify wildfires originated from Sentinel-2A and -2B, and Landsat-8 and -9. Fires have been grouped into two
classes based on detection period: summer fires and fall fires. Summer fires were detected between May 30 and September 17, and fall fires were
detected between September 17 and October 25. For summer fires, burned pixels were identified by TIIC as changed and typed as fire.
For the fall period, TIIC only detected changes within a 4-km buffer of NRCan fire perimeters (https://cwfis.cfs.nrcan.gc.ca/datamart). This
approach was used to limit commission errors that can occur due to known limitations of mapping with optical data in the fall due to phenology, snow
cover, or low sun angles. For the 2023 fire season, the TIIC algorithm detected 12.74 Mha of burned area in Canada’s forested ecozones, representing
1.8% of the total forest-dominated ecozone area. Of the 12.74 Mha, 11.57 Mha (90.9%) was burned by summer fires and 1.16 Mha (9.1%) by fall fires

# Canada Landsat Derived Wildfire disturbance & Magnitude 1985-2020
The annual forest change data included in this product is national in scope (entire forested ecosystem) and represents the wall-to-wall characterization of wildfire in Canada at a 30-m spatial resolution. The information outcomes represent 36 years of wildfire change over Canada’s forests, derived from a single, consistent, spatially explicit data source, derived in a fully automated manner. This demonstrated capacity to characterize forests at a resolution that captures human impacts is key to establishing a baseline for detailed monitoring of forested ecosystems from management and science perspectives. Time series of Landsat data were used to characterize national trends in stand replacing forest disturbances caused by wildfire and harvest for the period 1985–2020 for Canada's 650 Mha forested ecosystems.
Landsat data has a 30 m spatial resolution, so the change information is highly detailed and informative regarding both natural and human driven changes. These data represent annual stand replacing forest changes. The stand replacing disturbance types labeled are wildfire and harvest, with lower confidence wildfire and harvest, also shared. The distinction and sharing of lower class membership likelihoods is to indicate to users that some change events were more difficult to allocate to a change type, but are generally found to be in the correct category. For an overview on the data, image processing, and time series change detection methods applied, as well as information on independent accuracy assessment of the data, see ( Hermosilla et al. 2016). The data available is Change year for Wildfire Events. You can [download the dataset here](https://opendata.nfis.org/downloads/forest_change/CA_Forest_Fire_1985-2020.zip)
#### Canada Landsat-Derived Forest Wildfire Change Magnitude dNBR (1985-2020)
Wildfire change magnitude dNBR 1985-2020. Spectral change magnitude for wildfires that occurred from 1985 and 2020 expressed via differenced Normalized Burn Ratio (dNBR), computed as the variation between the spectral values before and after a given change event. This layer value has been transformed for data storage efficiency. The actual dNBR value can be calculated as follows dNBR = value / 100. Higher dNBR values are related to higher burn severity.

These time-series land cover maps were produced from annual time-series of Landsat image composites, forest change information, and ancillary topographic and hydrologic data following the framework described in Hermosilla et al. (2022), which builds upon the approach introduced in Hermosilla et al. (2018). The methodological innovations included (i) a refined training pool derived from existing land cover products using airborne and spaceborne measures of forest structure; (ii) selection of training samples proportionally to the land cover distribution using a distance=weighted approach; and (iii) generation of regional classification models using a 150x150 km tiling system. Maps are post-processed using disturbance information to ensure logical class transitions over time using a Hidden Markov Model. Hidden Markov Models assess individual year class likelihoods to reduce variability and possible noise in year-on-year class assignments (for instances when class likelihoods are similar).
For an overview on the data, image processing, and time series change detection methods applied, as well as information on independent accuracy assessment of the data, see Hermosilla et al. (2022) No. 112780. DOI: https://doi.org/10.1016/j.rse.2021.112780 and Hermosilla et al. (2018) https://www.tandfonline.com/doi/full/10.1080/07038992.2018.1437719
The data represents annual forest land cover of Canada's forested ecosystems for 1984-2022. An image compositing window of August 1 -30 days was used to generate the best-available-pixel (BAP) image composites used as the source data for land cover classification. The science and methods developed to generate the information outcomes shown here, that track and characterize the history of Canada's forests, were led by Canadian Forest Service of Natural Resources Canada, partnered with the University of British Columbia, with support from the Canadian Space Agency, augmented by processing capacity from WestGrid of Compute Canada.

### Projects Ca Sbfi (`docs/projects/ca_sbfi.md`)
# Canadian Satellite-Based Forest Inventory (SBFI)
The Satellite-Based Forest Inventory (SBFI) provides information on Canada’s forested land cover, disturbance recovery, structure, species, and stand age in 2020, as well as stand-replacing disturbances from 1985-2020. The SBFI polygons represent homogeneous forest conditions similar to those of stands delineated in a strategic forest inventory. More than 25 million SBFI polygons were delineated using a multiresolution segmentation algorithm applied to the 2020 Landsat surface-reflectance BAP image composite (30-m spatial resolution), fire year, and harvest year layers derived from Landsat using the C2C approach. A minimum map unit of 0.45 ha (5 pixels) was used to define polygons. The entirety of Canada’s forest ecosystems were mapped using the same data, attributes, and temporal representation, resulting in a common vegetation inventory system of Canada’s ~650 Mha forested ecosystems. Given the large and diverse forest area of Canada, the strength of an SBFI lies in the use of a consistent data source and methodology across jurisdictional boundaries, and managed and unmanaged forest areas, enabling consistently generated synoptic, spatially explicit information outputs. The data included herein are based upon free and open satellite data and information products following established and communicated approaches.

# High Resolution Tree Species Information for Canada
## Distance-to-second class for the leading tree species map
Distance-to-second class (D2SC) value used as indicator of attribution confidence for the leading tree species map produced from surface reflectance values in a spatially exhaustive, 30-m spatial resolution, Landsat image composite representing year 2019 conditions. Also included in the modeling of species are geographic and climate data, elevation derivatives, and remote sensing derived phenology following the framework described in Hermosilla et al. (2022). Regional classification models were generated based on Canada??s National Forest Inventory using a 150x150 km tiling system. D2SC is computed using the class membership probabilities derived from the first and second most voted classes from the Random Forests models.
## High Resolution Maps of tree species membership likelihood
Tree species maps indicate the class membership probability of all possible classes on a pixel level. The maps are generated using a 2019 Landsat image composite, geographic and climate data, elevation derivatives, and remote sensing derived phenology following the framework described in Hermosilla et al. (2022). Values represent the class membership probabilities derived from the Random Forests votes. Regional classification models were generated based on Canada??s National Forest Inventory (NFI) using a 150x150 km tiling system. The regional classification models utilize and aim to map only the trees species known to be present in a given tiling unit based on the information provided by the NFI.
## High Resolution Map of leading tree species distribution
Leading tree species map produced from a 2019 Landsat image composite, geographic and climate data, elevation derivatives, and remote sensing derived phenology following the framework described in Hermosilla et al. (xxxx). Regional classification models were generated based on Canada??s National Forest Inventory using a 150x150 km tiling system. The leading tree species are defined by representing the most voted tree species from the Random Forests classification models (i.e. the class with the highest class membership probability).
For an overview on the data, image processing, and methods applied, as well as information on independent accuracy assessment of the data, see Hermosilla et al. (2022) https://doi.org/10.1016/j.rse.2022.113276

### Projects Ca Species Ts (`docs/projects/ca_species_ts.md`)
# Canada Long Term Tree Species (1984-2022)
In this dataset, we share maps of annual dominant tree species (also known as leading tree species) from 1984-2022 covering the entirety of Canada’s 650 Mha forested ecosystems using Landsat time-series imagery at a 30-m spatial resolution. Classifications are based on regionally representative Random Forests model using local training samples from Canada’s National Forest Inventory (Hermosilla et al., 2022). Descriptive metrics provide information on spectral, geographic, climatic, and topographic characteristics. Initial annual tree species classifications were subjected to a time series post-classification process using the forward-backward Hidden Markov Model to improve the temporal consistency of tree species transitions within the time series. Assessment of the annual species maps using independent validation data resulted in an overall accuracy of 86.1% ± 0.14% (95%-confidence interval). These data allow consistent comparison of trends and rates of change in tree species composition nationally and across regions using a common time frame, spatial resolution, and analytical approach.

### Projects Caml (`docs/projects/caml.md`)
# Cyanobacteria Aggregated Manual Labels (CAML)
Continuous monitoring for cyanobacteria blooms in small, inland water bodies via in-situ sampling and analysis can be challenging not only due to the number and locations of
water bodies to cover, but also due to the dynamic nature of algal growth and toxin production. Detection targets vary with cyanobacteria strains as well as physical, chemical,
and biological factors. Ground monitoring also lacks consistency as sampling methods, frequency, and analytical techniques vary from region to region. However, remote sensing
allows systematic data collection over a large area to identify regions with potential harmful algal growth. We introduce the Cyanobacteria Aggregated Manual Labels (CAML), a
large dataset of in-situ cyanobacteria measurements for investigations of cyanobacteria detection and severity classification in inland water bodies across the United States.
Relevant satellite imagery from publicly available endpoints are applicable to use when applying the CAML dataset to models.
The dataset labels ground measurements of cyanobacteria cell counts at 23,570 points in U.S. inland water bodies over 2013 - 2021. Algorithms trained on this data could be used to estimate cyanobacteria cell counts in water bodies for timely water quality and public health interventions and to gain an understanding of environmental and anthropogenic factors associated with cyanobacteria
incidence and proliferation. Data is provided in a comma-separated values (CSV) format. You can find the dataset [here](https://seabass.gsfc.nasa.gov/archive/NASA_HEADQUARTERS/SGupta/CAML/CAML_2013_2021)
Severity levels are based on World Health Organization (WHO) cyanobacteria density thresholds.
* Low: 0 - 20,000 cells/ml
* Moderate: 20,000 - 100,000 cells/ml
* High: > 100,000 cells/ml
However users should feel free to to use their own thresholds as makes sense for their needs.

### Projects Can Drought Outlook (`docs/projects/can_drought_outlook.md`)
# Canadian Drought Outlook
The Canadian Drought Outlook raster dataset is produced by the Agriculture and Agri-Food Canada (AAFC). The Canadian Drought Outlook predicts whether drought across Canada will emerge, stay the same or get better over the target month. In calculating the outlook, consideration is given to Agroclimate indices, such as the Standard Precipitation Index (SPI), the Standard Precipitation Evaporation Index (SPEI), and the Palmer Drought Severity Index (PDSI). The drought outlook is issued on the first Thursday of each calendar month and is valid for 32 days from that date. You can get additional information about [this dataset here](https://open.canada.ca/data/en/dataset/2c82daab-f6d9-4b19-96b5-238249e09fb9) and on the [climate engine org dataset page here](https://support.climateengine.org/article/91-can-drought).

### Projects Canopy (`docs/projects/canopy.md`)
# ETH Global Sentinel-2 10m Canopy Height (2020)
The worldwide variation in vegetation height is fundamental to the global carbon cycle and central to the functioning of ecosystems and their biodiversity. Geospatially explicit and, ideally, highly resolved information is required to manage terrestrial ecosystems, mitigate climate change, and prevent biodiversity loss. Here, we present the first global, wall-to-wall canopy height map at 10 m ground sampling distance for the year 2020. No single data source meets these requirements: dedicated space missions like GEDI deliver sparse height data, with unprecedented coverage, whereas optical satellite images like Sentinel-2 offer dense observations globally, but cannot directly measure vertical structures. By fusing GEDI with Sentinel-2, we have developed a probabilistic deep learning model to retrieve canopy height from Sentinel-2 images anywhere on Earth, and to quantify the uncertainty in these estimates.
The presented approach reduces the saturation effect commonly encountered when estimating canopy height from satellite images, allowing to resolve tall canopies with likely high carbon stocks. According to our map, only 5% of the global landmass is covered by trees taller than 30 m. Such data play an important role for conservation, e.g., we find that only 34% of these tall canopies are located within protected areas. Our model enables consistent, uncertainty-informed worldwide mapping and supports an ongoing monitoring to detect change and inform decision making. The approach can serve ongoing efforts in forest conservation, and has the potential to foster advances in climate, carbon, and biodiversity modelling.

### Projects Carbon Projects (`docs/projects/carbon_projects.md`)
# Carbon Offset Project Boundaries
Nature-based climate solutions (NBS) have become an important component of strategies aiming to reduce atmospheric CO2 and mitigate climate change impacts. Carbon offsets have emerged as one of the most widely implemented NBS strategies, however, these projects have also been criticized for exaggerating offsets. Verifying the efficacy of NBS-derived carbon offset is complicated by a lack of readily available geospatial boundary data. Herein, we detail methods and present a database of nature-based offset project boundaries. This database provides the locations of 575 NBS projects distributed across 55 countries. Geospatial boundaries were aggregated using a combination of scraping data from carbon project registries (n=433, 75.3%) as well as manual georeferencing and digitization (n=127, 22.1%). Database entries include three varieties of carbon projects: avoided deforestation, afforestation, reforestation and re-vegetation, and improved forest management. An accuracy assessment of the georeferencing and digitizing process indicated a high degree of accuracy (intersection over union score of 0.98 +/- 0.015).
You can read the [dataset publication here](https://www.nature.com/articles/s41597-025-04868-2) and find the [dataset here](https://zenodo.org/records/11459391).
#### Database notes
- Users must carefully distinguish between overall project areas and project accounting areas based on their specific analysis requirements:
* The **project area** is defined as the geographical area where the project participants implement activities to reduce deforestation.
* The **project accounting area** is defined as the geographical area of the project that was used to calculate carbon credit issuance.
- This database does not represent a census of nature-based carbon projects and does not contain all varieties of nature-based carbon projects.
- Users should verify that any georeferencing inaccuracies will not significantly impact their analyses.
- The boundaries included in the database reflect the data available in the registries at the time of access, with some projects regularly updating their information.
- We note that we were unable to assess the accuracy of the boundaries constructed from linear features or from a developer provided protocol.

# Chesapeake Bay High Resolution Land Cover Dataset (2013-2014)
This raster dataset was developed as part of the Land Cover Project, a cooperative agreement between the Chesapeake Conservancy and the National Park Service funded through an interagency agreement with the Environmental Protection Agency. Virginia Geographic Information Network (VGIN) coordinated with Worldview Solutions the creation of a separate VA statewide high-resolution land cover dataset, which has unique class names and descriptions. For the purposes of a matching bay-wide dataset, this VA dataset was reclassified and some classes were edited to better match the Chesapeake Bay Dataset class definitions below.
High Resolution mapping was used to develop consistent and extremely accurate land cover dataset for all the counties that comprise the Chesapeake Bay watershed. This land cover was created based on 2014 National Agriculture Imagery Program (NAIP) aerial imagery.
Dataset created and developed by the Conservation Innovation Center at the Chesapeake Conservancy. The creation of this dataset was made possible as a result of a cooperative agreement between the Chesapeake Conservancy and the National Park Service being funded through an interagency agreement with the Environmental Protection Agency. This dataset will enhance the ability to guide the most efficient use of resources in the Bay as well as aid the identification of priorities for conservation and restoration. Created based on 2013/2014 National Agriculture Imagery Program (NAIP) aerial imagery.

# C-CAP High-Resolution Land Cover
The NOAA Coastal Change Analysis Program (C-CAP) produces national standardized land cover and change products for the coastal regions of the U.S. C-CAP products inventory coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring changes in these habitats. The timeframe for this metadata is summer 2016. These maps are developed utilizing high resolution National Agriculture Imagery Program (NAIP) imagery, and can be used to track changes in the landscape through time. This trend information gives important feedback to managers on the success or failure of management policies and programs and aid in developing a scientific understanding of the Earth system and its response to natural and human-induced changes. This understanding allows for the prediction of impacts due to these changes and the assessment of their cumulative effects, helping coastal resource managers make more informed regional decisions. NOAA C-CAP is a contributing member to the Multi-Resolution Land Characteristics consortium and C-CAP products are included as the coastal expression of land cover within the National Land Cover Database.
These detailed products bring NOAA’s national land cover mapping framework to the local level and are developed for specific project-based geographies (not the entire coastal land cover mapping boundary). Data are often developed in partnership with state and local groups. Attributes for this product are as follows: 0 Background, 1 Unclassified (Cloud, Shadow, etc), 2 Impervious, 3 4 5 Developed Open Space, 6 Cultivated Land, 7 Pasture/Hay, 8 Grassland, 9 Deciduous Forest, 10 Evergreen Forest, 11 Mixed Forest, 12 Scrub/Shrub, 13 Palustrine Forested Wetland, 14 Palustrine Scrub/Shrub Wetland, 15 Palustrine Emergent Wetland, 16 Estuarine Forested Wetland, 17 Estuarine Scrub/Shrub Wetland, 18 Estuarine Emergent Wetland, 19 Unconsolidated Shore, 20 Bare Land, 21 Open Water, 22 Palustrine Aquatic Bed, 23 Estuarine Aquatic Bed, 24 Tundra, 25 Snow/Ice, Recommended Citation.

### Projects Ccap Wpotential (`docs/projects/ccap_wpotential.md`)
# C-CAP Wetland Potential 30m
The probability rating which covers landcover mapping provides a continuum of wetness from dry to water. The layer is not a wetland classification but provides the wetland likelihood at a specific location. The rating was developed through a modelling process combining multiple GIS and remote sensing data sets including soil characteristics, elevation, existing wetland inventories, hydrographical extents and satellite imagery . Data can be [downloaded here](https://coast.noaa.gov/htdata/raster1/landcover/bulkdownload/wetlandpotential/). This classification is based on GIS and remote sensing data sets with variable ranges from the 1977 to 2010.
This dataset was created by NOAA's Ocean Service, Office for Coastal Management Initial Classification: 1m spatial resolution land cover data developed by the Chesapeake Bay Conservancy, University of Vermont Spatial Analysis Laboratory, and The Virginia Geographic Information Network (VGIN) was the starting point for this dataset. This product was developed using a Geographic Object-Based Image Analysis (GEOBIA) processing framework applied to NAIP imagery and Lidar data. This involves taking each image to be classified and grouping the pixels based on spectral and spatial properties into regions of homogeneity called objects. The resulting objects are the primary units for analysis. The original dataset can be downloaded here:https://chesapeakeconservancy.org/conservation-innovation-center/high-resolution-data/land-cover-data-project/.
The resulting 1-meter land cover was then resampled to a 10-meter raster. This was done using a 10x10 focal pixel window to compute the percent value associated with either the impervious or tree classes, for each land cover type in the 100 pixel neighborhood around each target pixel, and subsequently performing a nearest neighbor resampling of the resulting values. The output values were then coded to the appropriate percentage (between 0 and 100). This 10-meter raster was resampled a second time, using the average of values within a 3x3 focal pixel window in order to obtain the appropriate values over each 30-meter pixel area. Output values between 0 and 100 represent the appropriate percentage mapped within each pixel. Class 127 identifies areas not included in this mapping, or no data areas.
#### Class values
0: This is the value for nodata.
1: The value indicates there is an extremely low likelihood of wetness.
2-9: The value indicates a likelihood of wetness, where 1 is very unlikely and 9 is highly likely.
10: The value indicates open water.

### Projects Cci Agb (`docs/projects/cci_agb.md`)
# ESA CCI Global Forest Above Ground Biomass
This dataset updated to v6.0 provides estimates of forest above-ground biomass for the years 2007, 2010, 2015, 2016, 2017, 2018, 2019, 2020, 2021, and 2022. These estimates are derived from a combination of Earth observation data, depending on the year, obtained from the Copernicus Sentinel-1 mission, Envisat’s ASAR (Advanced Synthetic Aperture Radar) instrument, and JAXA's Advanced Land Observing Satellite (ALOS-1 and ALOS-2), along with additional information from other Earth observation sources. The dataset has been generated as part of the European Space Agency's (ESA's) Climate Change Initiative (CCI) program by the Biomass CCI team.
Compared to version 5, version 6 consists of updated AGB maps for the years 2010, 2015, 2016, 2017, 2018, 2019, 2020, 2021 and new AGB maps for 2007 and 2022. The dataset includes multi-temporal observations at L-band for all biomes and for each year. The above-ground biomass (AGB) maps utilize revised allometries, which are now based on a more extensive collection of spaceborne LiDAR data from the GEDI and ICESat-2 missions. The retrieval algorithm incorporates extended ICESat-2 observations to calibrate retrieval models and a refined cost function that preserves temporal features as expressed in the remote sensing data, limiting biases between the 2007-2010 and the 2015+ maps.
The data products consist of two (2) global layers that include estimates of:
1. Above ground biomass (AGB, unit: tons/ha i.e., Mg/ha) (raster dataset). This is defined as the mass, expressed as oven-dry weight of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots
2. Per-pixel estimates of above-ground biomass uncertainty expressed as the standard deviation in Mg/ha (raster dataset)
Additionally provided in this version release are aggregated data products. These aggregated products of the AGB and AGB change data layers are available at coarser resolutions (1, 10, 25 and 50km).
Also included are the change products which include these layers:
1. Standard deviation of AGB change: Maps showing the uncertainty of AGB change for consecutive years (e.g., 2016-2015, 2017-2016, 2018-2017, 2019-2018, 2020-2019, 2021-2020, 2022-2021), over a decade (2020-2010), and over the interval 2010-2007.
2. Quality flag of AGB change: Maps indicating the reliability of AGB change estimates for the same time periods mentioned above.
Note: AGB change values can be calculated by differencing the corresponding AGB maps. Data are provided in both netcdf and geotiff format.
Disclaimer: Whole or parts of the dataset description were provided by the author(s) or their works.
#### Dataset preprocessing for GEE
* Above ground biomass files were downloaded for each years as tiles and then merged into single year images rasters. Common metadata properties were preserved so as to be passed over to the collection
* The same approach for a yearly composite was applied to the Standard deviations tiles as well to make sure they can be mapped on top of each other.
* For ingestion a manifest file was created with Band 1 being AGB and Band 2 being SD so we could reduce the overall files for an image collection. The ingestion used a no data value of 0.
* For change product Band 1 was AGB_DIFF_SD and Band 2 was AGB_DIFF_QF and these were to represent standard deviation of AGB biomass change and quality flag of AGB biomass change.
* Metadata properties were copied over from AGB with some slight changes to fields and the dates were preprocessed and updated to v6.0.

### Projects Cci Lc (`docs/projects/cci_lc.md`)
# CCI LAND COVER S2 PROTOTYPE LAND COVER 20M MAP OF AFRICA 2016
The CCI Land Cover (LC) S2 prototype is a high resolution LC map at 20m over Africa based on 1 year of Sentinel-2A observations from December 2015 to December 2016. The main objective of the 'S2 prototype LC map at 20m of Africa 2016' release was to collect users feedback for further improvements. The Coordinate Reference System used for the global land cover database is a geographic coordinate system (GCS) based on the World Geodetic System 84 (WGS84) reference ellipsoid.
The legend of the S2 prototype LC 20m map of Africa 2016 was built after reviewing various existing typologies (e.g. LCCS, LCML…), global (e.g. GLC-share, GlobeLand30) and national experiences (Africover, SERVIR-RMCD). The legend includes 10 generic classes that appropriately describe the land surface at 20m: "trees cover areas", "shrubs cover areas", "grassland", "cropland", "vegetation aquatic or regularly flooded", "lichen and mosses / sparse vegetation", "bare areas", "built up areas", "snow and/or ice" and "open water".
Among the Land Cover classes, two of them were largely identified thanks to external dataset: the "open water" class was based on the Global Surface Water product from JRC/EC and the "urban areas" relied both on the Global Human Settlement Layer from JRC/EC and on the Global Urban Footprint from DLR. Two classification algorithms, the Random Forest (RF) and Machine Learning (ML), were chosen to transform the cloud-free reflectance composites generated by the pre-processing module into a land cover map. The two maps resulting from both approaches are then combined either to select the best representation of a land cover class which will be part of the final S2 prototype LC 20m map of Africa 2016 or, in case of unreliable LC class delineation, the reference layer is used to consolidate the land cover classification.

### Projects Cems Fire (`docs/projects/cems_fire.md`)
# CEMS Fire Danger Indices
Fire danger indices from the ECMWF, calculated using weather forecasts from historical simulations provided by ECMWF ERA5 reanalysis.The CEMS Fire Danger Indices dataset provides a comprehensive set of indices designed to assess and quantify fire danger and wildfire risk at regional and global scales. You can get additional information on the [dataset here](https://cds.climate.copernicus.eu/cdsapp#!/dataset/cems-fire-historical-v1?tab=overview) and on the [climateengine.org dataset page here](https://support.climateengine.org/article/49-cems-fire)
- Build-up Index: The Build-Up Index is a weighted combination of the Duff moisture code and Drought code to indicate the total amount of fuel available for combustion by a moving flame front. The Duff moisture code has the most influence on the Build-up index value. For example, a Duff moisture code value of zero always results in a Build-up index value of zero regardless of what the Drought code value is. The Drought code has the strongest influence on the Build-up index when Duff moisture code values are high. The greatest effect that the Drought code can have is to make the Build-up index value equal to twice the Duff moisture code value. The Build-up index is often used for pre-suppression planning purposes.
- Burning Index: The Burning Index measures the difficulty of controlling a fire. It is derived from a combination of Spread component (how fast it will spread) and Energy release component (how much energy will be produced). In this way, it is related to flame length, which, in the Fire Behavior Prediction System, is based on rate of spread and heat per unit area. However, because of differences in the calculations for Burning index and flame length, they are not the same.
- Drought Code: The Drought code is an indicator of the moisture content in deep compact organic layers. This code represents a fuel layer at approximately 10-20 cm deep. The Drought code fuels have a very slow drying rate, with a time lag of 52 days. The Drought code scale is open-ended, although the maximum value is about 800.
- Drought Factor: The drought factor is a component representing fuel availability. It is is given as a number between 0 and 10 and represents the influence of recent temperatures and rainfall events on fuel availability (see Griffiths 1998 for details). The Drought Factor is partly based on the soil moisture deficit which is commonly calculated in Australia as the Keetch-Byram Drought Index (KBDI) (also available). The KBDI estimates the soil moisture below saturation up to a maximum
- Duff Moisture Code: The Duff moisture code is an indicatore of the moisture content in loosely-compacted organic layers of moderate depth. It is representative of the duff layer that is 5-10 cm deep. Duff moisture code fuels are affected by rain, temperature and relative humidity. Because these fuels are below the forest floor surface, wind speed does not affect the fuel moisture content. The Duff moisture code fuels have a slower drying rate than the Fine fuel moisture code fuels, with a timelag of 12 days. Although the Duff moisture code has an open-ended scale, the highest probable value is in the range of 150.
- Energy Release Component: The Energy release component is a number related to the available energy (British Thermal Unit) per unit area (square foot) within the flaming front at the head of a fire. Daily variations in Energy release component are due to changes in moisture content of the various fuels present, both live and dead. Since this number represents the potential "heat release" per unit area in the flaming zone, it can provide guidance to several important fire activities. It may also be considered a composite fuel moisture value as it reflects the contribution that all live and dead fuels have to potential fire intensity. The Energy release component is a cumulative or "build-up" type of index. As live fuels cure and dead fuels dry, the Energy release component values get higher thus providing a good reflection of drought conditions. The scale is open-ended or unlimited and, as with other National Forest Danger Rating System components, is relative.
- Fine Fuel Moisture Code: The Fine fuel moisture code is an indicatore of the moisture content in litter and other cured fine fuels (needles, mosses, twigs less than 1 cm in diameter). The Fine fuel moisture code is representative of the top litter layer less than 1-2 cm deep. Fine fuel moisture code values change rapidly because of a high surface area to volume ratio, and direct exposure to changing environmental conditions. The Fine fuel moisture code scale ranges from 0-99 and is the only component of the Fire weather index system which does not have an open-ended scale. Generally, fires begin to ignite at Fine fuel moisture code values near 70, and the maximum probable value that will ever be achieved is 96.
- Fire Daily Severity Rating: Numeric rating of the difficulty of controlling fires. It is an exponential transformation of the Fire weather index and more accurately reflects the expected efforts required for fire suppression as it increases exponentially as the Fire weather index is above a certain value.
- Fire Danger Index: The Fire danger index is a metric related to the chances of a fire starting, its rate of spread, its intensity, and its difficulty of suppression. It is open ended however a value of 50 and above is considered extreme in most vegetation
- Fire Weather Index:The Fire weather index is a combination of Initial spread index and Build-up index, and is a numerical rating of the potential frontal fire intensity. In effect, it indicates fire intensity by combining the rate of fire spread with the amount of fuel being consumed. Fire weather index values are not upper bounded however a value of 50 is considered as extreme in many places. The Fire weather index is used for general public information about fire danger conditions.
- Ignition Component: The Ignition component measures the probability a firebrand will require suppression action. Since it is expressed as a probability, it ranges on a scale of 0 to 100. An Ignition component of 100 means that every firebrand will cause a fire requiring action if it contacts a receptive fuel. Likewise an Ignition component of 0 would mean that no firebrand would cause a fire requiring suppression action under those conditions.
- Initial Fire Spread Index: The Initial spread index combines the Fine fuel moisture code and wind speed to indicate the expected rate of fire spread. Generally, a 13 km h-1 increase in wind speed will double the Initial spread index value. The Initial spread index is accepted as a good indicator of fire spread in open light fuel stands with wind speeds up to 40 km h-1.
- Keetch-Byram Drought Index: The Keetch-Byram drought index (KBDI) is a number representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. It is a continuous index, relating to the flammability of organic material in the ground.The Keetch-Byram drought index attempts to measure the amount of precipitation necessary to return the soil to saturated conditions. It is a closed system ranging from 0 to 200 units and represents a moisture regime from 0 to 20 cm of water through the soil layer. At 20 cm of water, the Keetch-Byram drought index assumes saturation. Zero is the point of no moisture deficiency and 200 is the maximum drought that is possible. At any point along the scale, the index number indicates the amount of net rainfall that is required to reduce the index to zero, or saturation.
- Spread Component: The Spread component is a measure of the spead at which a headfire would spread. The spread component is numerically equal to the theoretical ideal rate of spread expressed in feet-per-minute however is considered as a dimensionless variable. The Spread component is expressed on an open-ended scale; thus it has no upper limit.

### Projects Cflux (`docs/projects/cflux.md`)
# Global Forest Carbon Fluxes (2001-2024)
Net forest carbon flux represents the net exchange of carbon between forests and the atmosphere between 2001 and 2024, calculated as the balance between carbon emitted by forests and removed by (or sequestered by) forests during the model period (megagrams CO2 emissions/ha). Net carbon flux is calculated by subtracting average annual gross removals from average annual gross emissions in each modeled pixel; negative values are where forests were net sinks of carbon and positive values are where forests were net sources of carbon between 2001 and 2024. Net fluxes are calculated following IPCC Guidelines for national greenhouse gas inventories in each pixel where forests existed in 2000 or were established between 2000 and 2020 according to the Global Forest Change tree cover change data of Hansen et al. (2013) and Potapov et al. (2022). This layer reflects the cumulative net flux during the model period (2001-2024) and must be divided by 24 to obtain average annual net flux; net flux values cannot be assigned to individual years of the model.
Forest carbon removals from the atmosphere (sequestration) by forest sinks represent the cumulative carbon captured (megagrams CO2/ha) by the growth of established and newly regrowing forests during the model period between 2001-2024. Removals include accumulation of carbon in both aboveground and belowground live tree biomass. Following IPCC Tier 1 assumptions for forests remaining forests, removals by dead wood, litter, and soil carbon pools are assumed to be zero. In each pixel, carbon removals are calculated following IPCC Guidelines for national greenhouse gas inventories where forests existed in 2000 or were established between 2000 and 2020 according to the Global Forest Change tree cover loss data of Hansen et al. (2013) and tree cover gain data of Potapov et al. (2022). Carbon removed by each pixel is based on maps of forest type (e.g., mangrove, plantation), ecozone (e.g., humid Neotropics), forest age (e.g., primary, old secondary), and number of years of carbon removal. This layer reflects the cumulative removals during the model period (2001-2024) and must be divided by 24 to obtain an annual average during the model duration; removal rates cannot be assigned to individual years of the model.
Forest carbon emissions represent the greenhouse gas emissions arising from stand-replacing forest disturbances that occurred in each modeled year (megagrams CO2 emissions/ha, between 2001 and 2023). Emissions include all relevant ecosystem carbon pools (aboveground biomass, belowground biomass, dead wood, litter, soil) and greenhouse gases (CO2, CH4, N2O). Emissions estimates for each pixel are calculated following IPCC Guidelines for national greenhouse gas inventories where stand-replacing disturbance occurred, as mapped in the Global Forest Change annual tree cover loss data of Hansen et al. (2013). The carbon emitted from each pixel is based on carbon densities in 2000, with adjustment for carbon accumulated between 2000 and the year of disturbance. Emissions reflect a gross estimate, i.e., carbon removals from subsequent regrowth are not included. Instead, gross carbon removals resulting from subsequent regrowth after clearing are accounted for in the companion forest carbon removals layer. The fraction of carbon emitted from each pixel upon disturbance (emission factor) is affected by several factors, including the direct driver of disturbance, whether fire was observed in the year of or preceding the observed disturbance event, whether the disturbance occurred on peat, and more. All emissions are assumed to occur in the year of disturbance. Emissions can be assigned to a specific year using the Hansen tree cover loss data.
All three layers are part of the forest carbon flux model described in [Harris et al. (2021)](https://www.nature.com/articles/s41558-020-00976-6) and updated in Gibbs et al. (2025). This paper introduces a geospatial monitoring framework for estimating global forest carbon fluxes which can assist governments and non-government actors with tracking greenhouse gas fluxes from forests and decreasing emissions or increasing removals by forests. All input layers were resampled to a common resolution of 0.00025 x 0.00025 degrees each to match Hansen et al. (2013). Please also find the dataset on [Global Forest Watch](https://gfw.global/3jLklJ9).

### Version 1.4.2 (2025)
**Major updates discussed in the [GFW blog post](https://www.globalforestwatch.org/blog/data/whats-new-carbon-flux-monitoring/)**
**Model Updates:**
- Updated to year 2024 tree cover loss data
- **Fire emission combustion factors:** Updated from 2006 IPCC Guidelines to 2019 Refinement values for boreal and temperate forests. This significantly reduces combustion factors in temperate forests where fires are associated with natural disturbances or unknown drivers
- **Soil carbon emission factors:** Updated stock-change factors for mineral soil with revised IPCC values. Factors are now higher for tropical forests when forests are converted to permanent agriculture
- **Emissions from mineralization of soil nitrogen:** Added N₂O emissions from soil nitrogen mineralization following IPCC guidelines where driver of tree cover loss is permanent agriculture, shifting cultivation, hard commodity production, or settlement and infrastructure
- **Higher resolution drivers of tree cover loss:** Updated from 10-km Curtis et al. 2018 map to 1-km Sims et al. 2025 map, including additional drivers at smaller spatial scales (natural disturbances other than wildfires, hard commodities like mining)

# Climate Hazards Group InfraRed Precipitation with Station Data-Prelim (CHIRPS-Prelim)
The Climate Hazards Center InfraRed Precipitation With Station Data-Prelim (CHIRPS-Prelim) is a blend of CHIRPS data with in situ precipitation data
to unbias the data and enhance its accuracy. The process of generating CHIRPS- Prelim is similar to the CHIRPS process, with the main difference
being its reliance on Global Telecommunication System (GTS) stations only, which are available in near-real time. Blending of CHIRP with GTS-only
stations allows for the latency of CHIRPS- Prelim to be <5 days. Note that, in general, the differences in CHIRPS-Prelim and CHIRPS are within
acceptable limits, as both data sets share the same climatological mean. You can find additional [information here](https://www.chc.ucsb.edu/data/chirps) and [on climate org dataset page here](https://support.climateengine.org/article/53-chirps).

Critical infrastructure (CI) is fundamental for the functioning of a society and forms the backbone for socio-economic development. Natural and human-made threats, however, pose a major risk to CI. Therefore, geospatial data on the location of CI are fundamental for in-depth risk analyses, which are required to inform policy decisions aiming to reduce risk. We present a first-of-its-kind globally harmonized spatial dataset for the representation of CI.
In this study the users generated: (1) a harmonized detailed geospatial data of the world’s main CI systems into a single geospatial database; and (2) a Critical Infrastructure Spatial Index (CISI) to express the global spatial intensity of CI. The datasets are generated from Open Streetmap extract from 8th January 2021 using https://planet.openstreetmap.org/. You can read the [full paper here](https://www.nature.com/articles/s41597-022-01218-4). You can download the spatial extracts for both the feature type and the Critical Infrastructure Spatial Index (CISI) [here](https://zenodo.org/record/4957647#.Yl5lhFzMJct)

### Projects Climate Trace (`docs/projects/climate_trace.md`)
# Climate Trace Global Emissions Data
Climate TRACE is a non-profit coalition that has unveiled an open emissions database containing more than 352 million assets. The database provides a comprehensive accounting of greenhouse gas (GHG) emissions based primarily on direct, independent observation. It includes every country and territory in the world and covers various emitting activities such as energy production, industrial processes, and land use. The data are derived from satellites, remote sensing, and other public and commercial sources, making it the most comprehensive and granular dataset of recent GHG emissions ever created. The inventory allows for transparent assessment of each country's progress toward emission reduction goals.
For more detailed information, you can visit the Climate TRACE website at [climatetrace.org](https://climatetrace.org).
#### Dataset preprocessing
The downloaded datasets were processed to get system:time_start and system:time_end in epoch time and these were added to the data column in GEE. Each sector and their associated emissions dataset sources were processed providing 38,731,650 total features. Not all sectors had emissions locations and some were provided only at a country level.

# CloudSEN12 Global dataset for semantic understanding of cloud and cloud shadow in Sentinel-2
CloudSEN12 is a large dataset for cloud semantic understanding that consists of 9880 regions of interest (ROIs) that consists of 49,400 image patches (IP) that are evenly spread throughout all continents except Antarctica. Each IP covers 5090 x 5090 meters and contains data from Sentinel-2 levels 1C and 2A, hand-crafted annotations of thick and thin clouds and cloud shadows, Sentinel-1 Synthetic Aperture Radar (SAR), digital elevation model, surface water occurrence, land cover classes, and cloud mask results from six cutting-edge cloud detection algorithms. Each ROI has five 5090x5090 meters image patches (IPs) collected on different dates that match one of the following cloud cover groups:
- clear (0%)
- low-cloudy (1% - 25%)
- almost clear (25% - 45%)
- mid-cloudy (45% - 65%)
- cloudy (65% >)

### Projects Cmapper (`docs/projects/cmapper.md`)
# Carbon Mapper Data Portal Methane Emissions
???+ note
**This dataset is currently only available to those in the [insiders program](https://gee-community-catalog.org/insiders/)**
The Carbon Mapper data portal focused on collecting individual high emission methane point sources. The [Carbon mapper portal](https://data.carbonmapper.org/) provides methane plume imagery with emission rates and uncertainties from strong point sources as observed from NASA’s next generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG) and ASU’s Global Airborne Observatory (GAO) airborne platforms.
As per the portal, these systems have near-identical capabilities and serve as prototypes for future sustained global monitoring. The plume concentration maps are available at spatial resolutions ranging from 3 to 8 meters (depending on aircraft altitude), allowing for precise attribution to individual emission sources.The API end point was used to query the overall area over North America yielding 8327 total sites.
You can use the download button too to download the curated zipped plume and geotiff data if you are inclined to use those. You can read [their FAQ here](https://carbonmapper.org/our-mission/faq/#data)
Disclaimer: Whole or parts of the dataset description were provided by the author(s) or their works.
#### Citation
As per the portal the following papers were used to generate the portal and the user should use the appropriate ones as deemed fit
```
/* Detailed source-code truncated for AI context efficiency. */
```
#### Data preprocessing
Based on the Plume extracts that were also available from the data portal certain assumptions and metadata fields were renamed. The campaign-id field was used a plume-id field for all of these observation. While there is a separate plume-id field in the original metadata it seems to be missing for some observations and as such the use of campaign id. This was also to keep alignment with the way in which the plume extracts were created by the data portal itself. Flux rate and Flux uncertainity were also renamed to emission and emission uncertainity.
The plume geotiffs were provided as RGB for rendering to a fixed hex code and color palette, so the metadata was attached to each of these raster geotiff in the collection. The portal also provided the RGB underlying imagery and that too was ingested in a separate collection with the same metadata for easy join. Finally the results were exported into a table, all downloaded for S3 URLs were automated using a custom script I wrote and included in the metadata.

### Projects Colombia Eq 2026 (`docs/projects/colombia_eq_2026.md`)
# Colombia Earthquake (Choco) 2026
On 10 August 2026 at 07:34 local time (12:34 UTC), a Mw 7.4 earthquake struck western Colombia, with an epicenter about 5 to 20 km south of San Jose del Palmar in Choco department (USGS puts it at Mw 7.4 and roughly 110 km depth, while the Global CMT project and the Colombian Geological Survey both report Mw 7.5). The rupture was an intermediate depth strike slip event within the subducting Nazca plate, and strong shaking (MMI VI to VII) was felt across a wide swath of western and central Colombia, reaching Cali, Pereira, Manizales, Armenia and Quibdo, as well as parts of Ecuador and Panama. Two independent commercial disaster response programs, Vantor's (formerly Maxar) open data program and Planet Labs' disaster data program, tasked satellite collections over the affected departments, and both are catalogued here as separate Earth Engine collections.
#### Event Summary
| Field | Value |
|---|---|
| Date / time | 10 August 2026, 07:34 local (12:34 UTC) |
| Magnitude | Mw 7.4 (USGS), Mw 7.5 (Global CMT, Colombian Geological Survey) |
| Depth | approximately 110 km, strike slip, subducting Nazca plate |
| Epicenter | 5 to 20 km south of San Jose del Palmar, Choco, Colombia (approximately 4.844 N, 76.242 W) |
| Deaths | at least 294 (consolidated figures as of mid August 2026) |
| Injured / missing | 3,900+ injured, 300+ still missing |
| Affected departments | Choco, Valle del Cauca, Risaralda, Quindio, Caldas, Antioquia, plus damage reported as far as Cali |
| Economic damage | estimates diverge widely, from roughly USD 1 to 2 billion (Oxford Economics) up to about USD 10 billion in other reporting, so no single figure is authoritative here |
Casualty and damage figures for an event this recent continue to move as recovery operations proceed. Check the sources listed below before quoting a number.
#### Vantor (Maxar) Open Data
Vantor's open data program released a pre-event baseline collection over the earthquake affected region, 19 images across 2 ingestion runs, all captured before the event (earliest scene 16 July 2026, no post-event imagery in this collection as of ingestion). Sensors are WorldView-2, WorldView-3, WorldView Legion (three separate satellites in the constellation) and GeoEye-1, at native resolutions from 0.35 to 3.26 m. Assets are full-strip cloud optimized GeoTIFFs with a visual band and a thumbnail per acquisition.

#### Planet Labs Disaster Data
Planet Labs' disaster data program released 157 images across 6 ingestion runs, combining a pre-event basemap with two distinct post-event collection phases. The pre-event baseline is drawn from Planet's Q2 2026 global quarterly basemap (1 April to 1 July 2026, roughly 4.8 m resolution). Post-event coverage was collected the same day and the following day as the earthquake: 57 PlanetScope scenes (approximately 3 m, collected the afternoon of 10 August 2026) spanning the cordillera from Risaralda south to Cauca, and skySat collects (approximately 0.66 m) over Quibdo, the Choco departmental capital, on 10 and 11 August 2026. Sensors are PlanetScope and SkySat, at resolutions from 0.66 to 4.78 m.

### Projects Csa (`docs/projects/csa.md`)
# CropSuite v1.0 Crop Suitability Assessment for Africa
CropSuite v1.0 is an open‑source tool that delivers high‑resolution crop‑suitability assessments for 48 species across the African continent, covering both rainfed and irrigated systems. The accompanying dataset, built for the historical window 1991‑2010, contains detailed suitability maps, climate suitability layers, identified limiting factors, estimates of multi‑cropping potential, and the optimal sowing windows for each crop. A central contribution of this work is the explicit incorporation of climate variability into the suitability calculations, offering a sharper picture for climate‑impact studies and agricultural decision‑making.
The modelling framework adopts a fuzzy‑logic formulation grounded in Liebig’s law of the minimum. By employing membership functions, it captures how each crop’s requirements intersect with a suite of climatic, edaphic, and topographic variables. With a spatial resolution of 30 arc‑seconds—roughly one kilometre—the model covers a broad portfolio of staples and cash crops, many of which have historically been overlooked in regional assessments, such as cassava, yam, millet, sorghum, cowpea, groundnuts, cocoa, coffee, oil palm, rubber, and banana.
Analyses of the resulting maps reveal that, across Africa, 5.7 million km² are highly suitable for cultivation, 10.6 million km² fall into a moderate suitability class, 3.3 million km² are marginal, and 10.4 million km² are deemed unsuitable. The zone between 10° N and 10° S offers a strong opportunity for multiple cropping, potentially supporting two or three harvests each year. In terms of sheer area, safflower leads with 16.82 million km² of suitable land, followed by sesame, guava, cowpea, and mango, which record 15.76, 14.15, 13.61, and 13.39 million km² respectively. When the model accounts for the dampening effect of climate variability, the overall area of suitable land shrinks by more than 2.2 million km², a reduction that is particularly pronounced in Somalia, Kenya, Ethiopia, South Africa, and the Maghreb countries of Morocco, Algeria, Tunisia, and Libya.
#### Dataset Description
The CropSuite v1.0 dataset provides comprehensive crop suitability information at 30 arcsec spatial resolution (approximately 1 km at the Equator) for Africa. The dataset uses:
* **Climate Data**: CHIRPS v2.0 daily precipitation and CHIRTS v1.0 daily temperature (1991-2010)
* **Soil Data**: ISRIC SoilGrids (250m-1000m), WISE database, and ISRIC Global Soil Salinity Map
* **Terrain Data**: SRTM elevation data
* **Irrigation**: Current irrigated areas based on Meier et al. (2018)
The model accounts for:
- Climate variability and recurrence rate of potential crop failure
- Irrigated and rainfed agricultural systems
- Vernalization requirements for winter crops
- Lethal temperature thresholds
- Photoperiodic sensitivity
- Multiple cropping potential
- Optimal sowing and harvest dates
The data is organized into 10 thematic collections, with each collection containing 6 scenarios representing different water conditions (rainfed, irrigated, combined) and climate variability considerations (with/without).
#### Crops Included (48 Total)
Alfalfa, Arabica Coffee, Avocado, Banana, Barley, Beans, Cabbage, Carrot, Cashew, Cassava, Castor Bean, Chickpea, Citrus, Cocoa, Coconut, Cotton, Cowpea, Green Pepper, Groundnut, Guava, Maize, Mango, Millet, Oil Palm, Olive, Onion, Papaya, Pea, Pineapple, Potato, Rapeseed, Rice, Robusta Coffee, Rubber tree, Rye, Safflower, Sesame, Sorghum, Soy, Sugar Cane, Sunflower, Sweet Potato, Tea, Tobacco, Tomato, Watermelon, Wheat, Yam
#### Available Collections and Layers
The dataset is organized into 10 thematic ImageCollections, each containing 6 scenario images:
**Collections:**
1. `climate_suitability` - Climate suitability index for each crop

# USDA Crop Sequence Boundaries 2018-2025
The **Crop Sequence Boundaries (CSB)**, developed in collaboration with the USDA's Economic Research Service, provides estimates of field boundaries, crop acreage, and crop rotations across the contiguous United States. This dataset utilizes satellite imagery along with other public data and is open source, enabling users to conduct area and statistical analysis of planted U.S. commodities. It offers valuable insights into farmer cropping decisions and practices.
NASS required a representative field dataset for predicting crop planting based on common rotations like corn-soy, while the Economic Research Service (ERS) employs the CSB to study changes in farm management practices such as tillage and cover cropping over time. The CSB dataset represents non-confidential single crop field boundaries within a specified timeframe. It does not include personal identifying information, ownership boundaries, or tax parcels. The data is sourced from satellite imagery and publicly available information, excluding contributions from producers or agencies like the Farm Service Agency. For access and further information, you can visit the [CSB website](https://www.nass.usda.gov/Research_and_Science/Crop-Sequence-Boundaries/index.php). Explore the [CSB GitHub repository](https://github.com/USDA-REE-NASS/crop-sequence-boundaries) for the codebase, and review the [metadata](https://www.nass.usda.gov/Research_and_Science/Crop-Sequence-Boundaries/metadata_Crop-Sequence-Boundaries-2025.htm) associated with the dataset.
Crop Sequence Boundaries (CSB) represent geospatial algorithm-generated field polygons, originating from the NASS Cropland Data Layer (CDL). These polygonal entities cater to the demands of applications reliant on gridded datasets, necessitating analytical units for streamlined data aggregation. The primary objective of CSBs is to furnish comprehensive coverage spanning the contiguous 48 United States, ensuring precision and replicability across multiple years. These structures are forged by amalgamating historical CDLs within a specified time frame, while also integrating road and rail networks to accurately depict crop sequences within these simulated fields. The most recent eight-year window covers the 2018 to 2025 growing seasons, and the full archive of eight-year windows runs from 2008-2015 onward.

#### Dataset structure and preprocessing
The datasets are made available as feature collections in Earth Engine for each state, where the 1825 in the collection name represents the 2018-2025 growing seasons. The state names are part of the feature collection name. While it may not be necessary it is possible to merge them into a single collection for those who would want to run some analysis on a combined feature collection.
Note that the state collections for this window carry crop history attributes for CDL years 2018 through 2025 (for example `CROP18` through `CROP25`), so scripts written against the 2016-2023 assets need their attribute names updated as well as their paths.

### Projects Csi (`docs/projects/csi.md`)
# Carbon Security Index
This dataset presents an index developed to assess carbon security across the sagebrush steppe in the Great Basin. The Carbon Security Index (CSI) incorporates data from three key sources: fractional plant cover from the [Rangeland Analysis Platform](https://rangelands.app/), a fire probability model specific to the Great Basin (Smith et al., 2023), and a resistance and resilience dataset for the sagebrush steppe (Chambers et al., 2014, 2017).
The CSI is calculated as follows:
**CSI = Preferred Rangeland Cover Index + Resistance & Resilience – P(Fire)**
The resulting index ranges from -2 to +2 and allows for spatial comparisons of carbon security across the region.

### Projects Ctrees Amazon (`docs/projects/ctrees_amazon.md`)
# High Resolution Amazon Canopy Tree Height Dataset
This dataset provides high-resolution (~4.78 m) tree canopy height for the Amazon forest for the period 2020-2024. It was generated using a U-Net deep learning model adapted for regression, trained with Planet NICFI satellite images and informed by LiDAR-derived canopy height models (CHMs). The model predicts mean tree canopy height and has demonstrated a mean error of 3.68 m in validation samples, successfully estimating canopy heights up to 40-50 m with relatively low systematic bias. The study determined that the Amazon forest has an average canopy height of approximately 22 m. You can find additional information [in the preprint](https://arxiv.org/abs/2501.10600)
#### Key Features and Details
**Spatial Resolution:** ~4.78 meters
**Temporal Coverage:** Composite for 2020-2024. The model was trained using Planet NICFI images from 2015-12-01 to 2024-06-01 and LiDAR data collected between 2008 and 2018. The final Amazon forest map is a mean for the period 2020-2024.
**Coverage:** Amazon forest domain (approximately 8,260,920 km²)
**Accuracy:** Mean Absolute Error (MAE) of 3.68 m on validation samples. The model estimates heights up to 40-50 m without significant saturation.
**Data Format:** To obtain the actual height in meters, the pixel values in the asset must be divided by 2.5. The original CHM was multiplied by 2.5 and saved as integer 8 bits.
**Mean Amazon Canopy Height:** Estimated at ~22.09 m
#### Data Sources

### Projects Ctrees Global (`docs/projects/ctrees_global.md`)
# CTrees Global Aboveground Biomass 100m (2000–2025)
!!! note "Preprint Notice"
This dataset is associated with a **non-peer-reviewed preprint** submitted to EarthArXiv (May 7, 2026). The methodology and results have not yet undergone formal peer review. Users are encouraged to review the [preprint](https://doi.org/10.31223/X5KJ4Q) directly and exercise appropriate caution when citing or applying this dataset in research. This page will be updated once this has been published
Accurate, high-resolution estimation of forest aboveground biomass (AGB) is critical for quantifying terrestrial carbon stocks and informing climate mitigation policy, yet existing global products remain constrained by coarse spatial resolution and limited temporal coverage. This dataset from [CTrees](https://ctrees.org) presents a wall-to-wall global AGB product at **100 m native spatial resolution spanning 2000–2025**, trained with a DenseNet deep learning architecture using independent AGB reference labels from ALS-derived AGB, field-plot and forest-inventory samples from the research community, selected regional and national inventories, and mangrove AGB training samples from global coastal regions. The predictor stack integrates Landsat surface reflectance time series, ALOS PALSAR-1/2 L-band backscatter, GEDI and ICESat-2 canopy-height metrics (used only as ancillary structural layers), and topographic data. On a held-out validation set of approximately 1.01 million pixels compiled across eco-regions, the product achieves **R² = 0.741, RMSE = 59.5 Mg ha⁻¹, and bias = −4.82 Mg ha⁻¹**. Further details about the dataset and underlying methodology can be found in the [CTrees AGB Carbon Data Brief](https://ctrees-website.s3.us-west-2.amazonaws.com/news/26_04+AGB+Carbon+Data+Brief.pdf).
#### Band Description
Each annual image in the collection contains two bands. Raw pixel values are stored as **signed int16 with a scale factor of 0.1**; divide raw values by 10 to obtain values in Mg ha⁻¹.
| Band | Units | Scale Factor | Description |
|------|-------|-------------|-------------|
| **agb** | Mg/ha | 0.1 | Aboveground biomass of dry matter in live woody vegetation. Generated by a cluster-aware DenseNet framework integrating Landsat optical imagery, ALOS PALSAR L-band microwave backscatter, and lidar/field reference data to translate structural height metrics into biomass density. |
| **uncertainty** | Mg/ha | 0.1 | Pixel-level residual uncertainty in AGB estimates. Uncertainty grows with biomass magnitude, consistent with optical and SAR saturation in dense-canopy conditions. |
!!! warning "Scale Factor"
Raw pixel values must be divided by **10** to obtain true AGB values in Mg/ha (e.g., a raw value of 352 = 35.2 Mg/ha).
For conversion to **carbon (C)**, multiply AGB by **0.5**.
For conversion to **CO₂ equivalent**, multiply carbon by **3.667**.
#### Image Properties
Each image carries the following metadata properties:
| Property | Value | Description |
|----------|-------|-------------|
| `agb_scale_factor` | 0.1 | Multiply raw AGB band values by this factor |
| `agb_units` | Mg/ha | Units after applying scale factor |
| `uncertainty_scale_factor` | 0.1 | Multiply raw uncertainty band values by this factor |
| `uncertainty_units` | Mg/ha | Units after applying scale factor |
| `carbon_conversion_factor` | 0.5 | Multiply AGB by this to get carbon mass |
| `co2e_conversion_factor` | 3.667 | Multiply carbon by this to get CO₂ equivalent |
| `spatial_resolution_m` | 100 | Native spatial resolution in meters |
| `year` | e.g. 2000 | Year of the annual AGB estimate |

### Projects Cygnss (`docs/projects/cygnss.md`)
# CYGNSS Fractional Inundation
Data span August 2018 to December 2025 at 3 km resolution, with daily files representing either daily or 3-daily aggregated interpolated data. Coverage is limited to ±38 degrees latitude by the CYGNSS orbital inclination.
The UCAR/CU CYGNSS inundation maps provide fractional surface water extent derived from NASA's Cyclone Global Navigation Satellite System (CYGNSS), a constellation of eight microsatellites launched in December 2016. Each satellite carries a GNSS-Reflectometry (GNSS-R) receiver that records L-band GPS signals reflected from the Earth's surface. Because the transmitters are already on orbit, GNSS-R receivers are inexpensive to build and fly, which makes constellations — and therefore short revisit times — practical in a way that single-satellite radars are not. Surface reflectivity (Γ) at L-band is sensitive to the dielectric constant and micro-scale roughness of the reflecting surface, both of which change sharply when a landscape floods.
Inundation fraction is retrieved by treating the observed reflectivity of a 3 km grid cell as the weighted average of the reflectivity of its inundated and un-inundated fractions, with the weights equal to the respective cell fractions. Inverting this relationship requires ancillary estimates of soil moisture (SMAP L3 Enhanced), soil surface roughness, water surface roughness, and an empirical correction for the attenuating effect of above-ground biomass. Soil and water roughness are parameterized as spatially varying but temporally static fields calibrated against 2018 observations; soil moisture varies through time.
Because the eight satellites sample the surface pseudo-randomly and cannot completely cover it within a few days, observations are aggregated over 3-day windows and spatially interpolated using the Previously-Observed Behavior Interpolation (POBI) method, which derives historical relationships between reflectivity in neighboring grid cells and applies them to unobserved cells. POBI is an exact interpolator — observed values are unchanged — so users who prefer to avoid interpolated data can restrict their analysis to observed cells using the interpolation flag band.
Data span August 2018 to December 2025 present at 3 km resolution, with daily files representing the mean inundation fraction for the current day and previous two days. Coverage is limited to ±38 degrees latitude by the CYGNSS orbital inclination.

| Band | Description | Units |
| --- | --- | --- |
| inundation_1day | 1-day CYGNSS inundation fraction, observed cells only | %, divide by 100 for fraction |
| inundation_3day | 3-day CYGNSS average inundation fraction, interpolated onto a regular grid | %, divide by 100 for fraction |
| interpolation_flag | Whether a grid cell is interpolated (1) or observed (0) | None |

| inundation_anomaly_3day | 3-day average inundation anomaly, interpolated onto a regular grid | %, subtract 100 then divide by 100 |
All bands use 255 as the fill value. Anomaly bands carry a +100 bias so that negative anomalies can be stored in an unsigned type — subtract 100 before converting to fractional inundation. Anomalies are computed relative to a long-term baseline climatology.

| system:time_end | UTC midnight of the following day (exclusive) |
#### Uncertainty and Known Limitations
??? example "Users should be aware of the following sources of uncertainty"
| Source | Effect |
| --- | --- |
| Reflectivity calibration | Uncertainty in Γ is roughly ±1.74 dB, much of it attributable to GPS satellites switching to 'flex power mode' in February 2020. CYGNSS data are not calibrated for land remote sensing, which can bias entire tracks up or down. |
| Water roughness | The largest known unknown. Water roughness is held temporally static, but varies with wind. Where surface water is rougher than the parameterized value, inundation is under-retrieved. |
| Soil moisture | SMAP retrievals are themselves biased high by surface water, and high soil moisture values push the retrieval toward underestimating inundation during floods. |
| High inundation fractions | Reflectivity becomes progressively less sensitive to inundation as fraction rises above ~0.5, so small errors in Γ can translate into inundation differences greater than 0.3. |
| Dense vegetation | Retrievals underestimate inundation in flooded forest; the biomass correction does not account for seasonal canopy water content or structure. |
| Complex terrain | Isolated cells with anomalously high inundation appear in mountainous regions, resembling speckle noise. |
| Spatial interpolation | POBI performs best where inundation follows historical patterns and less well during floods with return intervals longer than the 2017-2018 training period. |
Compared against PALSAR-2 over the Amazon, retrievals agree closely (RMSD 0.07, r² of 0.91) but underestimate at high water fractions. Against the Dartmouth Flood Observatory for Cyclone Idai, mean inundation was 0.06 low with an RMSD of 0.16. Incorporating several inundation sources is likely to be more informative than relying on any one alone.
#### Data Access
The source netCDF files are hosted on the [COSMIC data server](https://data.cosmic.ucar.edu/gnss-r/inundation/cygnss/level3/). The Earth Engine collection hosts the same retrievals converted to Cloud-Optimized GeoTIFF and updated to present day.

### Projects Daily Lst (`docs/projects/daily_lst.md`)
# MODIS Gap filled Long-term Land Surface Temperature Daily (2003-2020)
High spatiotemporal land surface temperature (LST) datasets are increasingly needed in a variety of fields such as ecology, hydrology, meteorology, epidemiology, and energy systems. In this study the authors developed a novel spatiotemporal gap-filling framework by implementing data preprocessing (filtering pixels with low data quality and gap-filling missing values at one overpass using values at one of the other three overpasses each day) and spatiotemporal fitting (filtering the long-term trend (overall mean) of observations in each pixel, and then spatiotemporally interpolating residuals between observations and overall mean values for each day, and finally adding the overall mean and interpolated residuals), to generate a seamless high spatiotemporal LST dataset using the four daily LST observations from the two MODIS instruments on Terra and Aqua satellites. The paper on the gap-filling method will be published in near future.
The method was implemented to create a global gap filled LST observation.. The cross-validation indicates that the average root mean squared error (RMSE) for mid-daytime (1:30pm) and mid-nighttime (1:30am) LST is 1.88K and 1.33K, respectively. The gap-filled LST in the unit of 0.1 Celsius temperature (0.1 degree C) .You can read the [abstract here](https://ui.adsabs.harvard.edu/abs/2020AGUFMGC127..01Z/abstract)

### Projects Dea Croplands (`docs/projects/dea_croplands.md`)
# Digital Earth Africa's cropland extent map Africa 2019
These maps shows the estimated location of croplands in the following countries for the period January to December 2019 where cropland is defined as a piece of land of minimum 0.01 ha (a single 10m x 10m pixel) that is sowed/planted and harvestable at least once within the 12 months after the sowing/planting date. It was also noted that "This definition will exclude non-planted grazing lands and perennial crops which can be difficult for satellite imagery to differentiate from natural vegetation." The provisional cropland extent maps have a resolution of 10 metres, and were built using Copernicus Sentinel-2 satellite images from 2019. The cropland extent maps were built seperately using extensive training data from Eastern, Western, Northern, and Sahel Africa, coupled with a Random Forest machine learning model. A detailed exploration of the methods used to produce the cropland extent map can be found in the [Jupyter Notebooks in DE Africa’s crop-mask](https://github.com/digitalearthafrica/crop-mask). Easiest place to download the datasets is from [AWS Open data registry](https://registry.opendata.aws/deafrica-crop-extent/)
* crop_mask: Entire African continent
* crop_mask_eastern: Tanzania, Kenya, Uganda, Ethiopia, Rwanda, and Burundi
* crop_mask_western: Nigeria, Benin, Togo, Ghana, Cote d’Ivoire, Liberia, Sierra Leone, Guinea, and Guinea-Bissau
* crop_mask_northern: Morocco, Algeria, Tunisia, Libya, and Egypt
* crop_mask_sahel: Mauritania, Senegal, Gambia, Mali, Burkina Faso, Niger, Chad, Sudan, South Sudan, Somalia, and Djibouti
* crop_mask_southern: South Africa, Namibia, Botswana, Lesotho, and Eswanti
* crop_mask_southeast: Zimbabwe, Zambia, Mozambique, and Malawi
* crop_mask_central: Angola, Democratic Republic of the Congo, Congo, Gabon, Cameroon, Equatorial Guinea, and Central African Republic
* crop_mask_indian_ocean: Madagascar, Mauritius, Reunion, and Comoros
The products contain three measurements:
* mask: This band displays cropped regions as a binary map. Values of 1 indicate the presence of crops, while a value of 0 indicates the absence of cropping. This band is a pixel-based cropland extent map, meaning the map displays the raw output of the pixel-based Random Forest classification.
* prob: This band displays the prediction probabilities for the ‘crop’ class. As this service uses a random forest classifier, the prediction probabilities refer to the percentage of trees that voted for the random forest classification. For example, if the model had 200 decision trees in the random forest, and 150 of the trees voted ‘crop’, the prediction probability is 150 / 200 x 100 = 75 %. Thresholding this band at > 50 % will produce a map identical to mask.
* filtered: This band displays cropped regions as a binary map. Values of 1 indicate the presence of crops, while a value of 0 indicates the absence of cropping. This band is an object-based cropland extent map where the mask band has been filtered using an image segmentation algorithm [see this paper for details on the algorithm used](https://www.mdpi.com/2072-4292/6/7/6111/htm). During this process, segments smaller than 1 Ha (100 10m x 10m pixels) are merged with neighbouring segments, resulting in a map where the smallest classified region is 1 Ha in size. The filtered dataset is provided as a complement to the mask band; small commission errors are removed by object-based filtering, and the ‘salt and pepper’ effect typical of classifying pixels is diminished.
|Band ID |Description |Value range|Data type|NoData/Fill value|
|--------|--------------------------|-----------|---------|-----------------|
|mask |crop extent (pixel) |0 - 1 |uint8 |0 |
|prob |crop probability (pixel) |0 - 100 |uint8 |0 |
|filtered|crop extent (object-based)|0 - 1 |uint8 |0 |

### Projects Dea Lc (`docs/projects/dea_lc.md`)
# Digital Earth Australia(DEA) Landsat Land Cover 25m v1.0.0
Land cover is the observed physical cover on the Earth's surface including trees, shrubs, grasses, soils, exposed rocks, water bodies, plantations, crops and built structures. A consistent, Australia-wide land cover product helps understanding of how the different parts of the environment change and inter-relate. Earth observation data recorded over a period of time firstly allows the observation of the state of land cover at a specific time and secondly the way that land cover changes by comparison between times.
DEA Land Cover provides annual land cover classifications for Australia using the Food and Agriculture Organisation Land Cover Classification System taxonomy Version 2 (Di Gregorio and Jansen, 1998; 2005). DEA Land Cover classifications have been generated by combining quantitative (continuous) or qualitative (thematic) environmental information (referred to as Essential Descriptors; EDs) derived from Landsat satellite sensor data. Several EDs have been generated previously by Geoscience Australia, including annual water summaries (Mueller et al., 2016), vegetation fractional cover (Scarth et al., 2010), mangrove extent (Lymburner et al., 2020) and the Inter Tidal Extent Model (ITEM; Sagar et al., 2017), whilst others have been developed more recently. These EDs have been combined to generate detailed, consistent and expandable annual classifications of Australia’s land cover from 1988 through to 2020.
Additional information including descriptors above [can be found here](https://cmi.ga.gov.au/data-products/dea/607/dea-land-cover-landsat) and you can also [explore the map here](https://maps.dea.ga.gov.au)
Disclaimer: Parts or all of the dataset description is borrowed from existing description provided by authors.
#### Data preprocessing
Datasets were downloaded from Amazon S3 buckets and each years tiles were composited to create single year derivatives. Start and end date for years were also added to metadata and the collection included the version 1.0.0 as v100. Since this is a classified imagery MODE pyramiding scheme was used and default nodata value from tif at 0 was utilized for no data value during upload.

### Projects Dea Shorlines (`docs/projects/dea_shorlines.md`)
# Digital Earth Australia Coastlines
Digital Earth Australia Coastlines is a continental dataset that includes annual shorelines and rates of coastal change along the entire Australian coastline from 1988 to the present. The product combines satellite data from Geoscience Australia's Digital Earth Australia program with tidal modelling to map the most representative location of the shoreline at mean sea level for each year. The product enables trends of coastal retreat and growth to be examined annually at both a local and continental scale, and for patterns of coastal change to be mapped historically and updated regularly as data continues to be acquired. This allows current rates of coastal change to be compared with that observed in previous years or decades.
The ability to map shoreline positions for each year provides valuable insights into whether changes to our coastline are the result of particular events or actions, or a process of more gradual change over time. This information can enable scientists, managers and policy makers to assess impacts from the range of drivers impacting our coastlines and potentially assist planning and forecasting for future scenarios. You can find [additional details here](https://cmi.ga.gov.au/data-products/dea/581/dea-coastlines) and you can [download the datasets here](https://data.dea.ga.gov.au/?prefix=derivative/dea_coastlines/3-0-0/)
Disclaimer: Whole or parts of the dataset description were provided by the author(s) or their works.
Annual shoreline vectors that represent the median or ‘most representative’ position of the shoreline at approximately 0 m Above Mean Sea Level for each year since 1988. Dashed shorelines have low certainty and Annual shorelines include the following attribute fields:
| **Attribute** | **Description** |
|-----------------|---------------------------------------------------------------------------------|
| **year** | The year of each annual shoreline. |
| **certainty** | A column providing important data quality flags for each annual shoreline. |
| **tide_datum** | The tide datum of each annual shoreline (e.g. “0 m AMSL”). |
| **id_primary** | The name of the annual shoreline’s Primary sediment compartment from the Australian Coastal Sediment Compartments framework. |

### Projects Deaf Shorlines (`docs/projects/deaf_shorlines.md`)
# Digital Earth Africa Coastlines
The Digital Earth Africa Coastlines is a continental dataset that includes annual shorelines and rates of coastal change along the entire African coastline. This is a provisional service that has been generated for 2000 to 2021 and we would like to improve and operationalize with users.
The product combines satellite data from the Digital Earth Africa program with tidal modelling to map the typical location of the coastline at mean sea level each year. The product enables trends of coastal erosion and growth to be examined annually at both a local and continental scale, and for patterns of coastal change to be mapped historically and updated regularly as data continues to be acquired. This allows current rates of coastal change to be compared with that observed in previous years or decades.
The ability to map shoreline positions for each year provides valuable insights into whether changes to the coastline are the result of particular events or actions, or a process of more gradual change over time. This information can enable scientists, managers, and policy makers to assess impact from the range of drivers impacting the coastlines and potentially assist planning and forecasting for future scenarios. You can find [additional details here](https://docs.digitalearthafrica.org/en/latest/data_specs/Coastlines_specs.html) and you can [download the datasets here](https://docs.digitalearthafrica.org/en/latest/data_specs/Coastlines_specs.html#Data-Access)
#### Acknowledgment
The Coastlines algorithms incorporated in this product are the work of Robbi-Bishop Taylor, Rachel Nanson, Stephen Sagar, and Leo Lymburner, Geoscience Australia. Digital Earth Africa acknowledges the work done by the Centre de Suivi Ecologique (CSE), Dakar, in assessing the accuracy of the service with the participation of West African WACA stakeholders.

### Projects Delta Dtm (`docs/projects/delta_dtm.md`)
# DeltaDTM Global coastal digital terrain model
DeltaDTM is a global coastal Digital Terrain Model (DTM) with a horizontal spatial resolution of 1 arcsecond (∼30 m) and a vertical mean absolute error (MAE) of 0.43 m overall. It improves upon the accuracy of existing global elevation datasets by correcting Copernicus DEM with spaceborne lidar data from the ICESat-2 and GEDI missions. This correction process involves bias correction, filtering of non-terrain cells (e.g., vegetation and buildings), and gap filling using interpolation. DeltaDTM specifically focuses on low-lying coastal areas (below 30 m above Mean Sea Level) that are particularly vulnerable to sea-level rise, subsidence, and extreme weather events.
DeltaDTM is a valuable resource for a wide range of applications, including coastal management, flood modeling, and adaptation planning. Its improved accuracy enables more precise assessments of coastal flood risks and supports the development of effective mitigation and adaptation strategies. The dataset is freely available in the public domain and can be easily accessed and utilized by researchers, policymakers, and coastal communities. You can read the [paper here](https://www.nature.com/articles/s41597-024-03091-9) and download the [dataset here](https://data.4tu.nl/datasets/1da2e70f-6c4d-4b03-86bd-b53e789cc629).

### Projects Dynqual (`docs/projects/dynqual.md`)
# DynQual Global Surface Water Quality Dataset
Maintaining optimal surface water quality is essential for preserving ecosystems and ensuring safe human water utilization. However, our understanding of surface water quality relies heavily on data from monitoring stations, which are spatially limited and temporally fragmented. Addressing these limitations, we introduce the dynamical surface water quality model (DynQual). This model offers simulations of water temperature (Tw), as well as concentrations of total dissolved solids (TDS), biological oxygen demand (BOD), and fecal coliform (FC). DynQual operates at a daily time step and boasts a spatial resolution of 5 arcmin (∼ 10 km).
This comprehensive global model allows us to evaluate its performance against real-world water quality observations. In addition, we present insights into spatial patterns and temporal trends of TDS, BOD, and FC concentrations spanning the years 1980 to 2019. Our analysis identifies dominant sectors contributing to surface water pollution. Remarkably, DynQual reveals widespread multi-pollutant hotspots, particularly in northern India and eastern China, though water quality issues extend across all regions worldwide. The most significant declines in water quality have occurred in developing regions, especially sub-Saharan Africa and South Asia. Researchers can access the open-source model code (Jones et al., 2023) as well as the global datasets encompassing simulated hydrology, Tw, TDS, BOD, and FC at 5 arcmin resolution on a monthly basis (Jones et al., 2022b). These datasets hold the potential to enhance diverse studies ranging from ecological research to human health and water scarcity assessments. Discover more at [DynQual Model Code](https://doi.org/10.5281/zenodo.7932317) and [Global Surface Water Quality Datasets](https://doi.org/10.5281/zenodo.7139222). You can read [the full paper here](https://gmd.copernicus.org/articles/16/4481/2023/)
The constituents, such as total dissolved solids (TDS), biological oxygen demand (BOD), and fecal coliform (FC), are concentrations. The routed versions of these constituents (routed_TDS, routed_BOD, and routed_FC) are masses of pollutants. These values represent the pollution without considering dilution, and therefore more accurately reflect the transport or "export" of pollution through the river network.
**Please refer to the original paper on guidance on displaying the concentration maps, the authors recommend these are only plotted above a given discharge/channelStorage threshold**
Disclaimer: Whole or parts of the dataset description were provided by the author(s) or their works.
#### Datasets preprocessing
The datasets were downloaded and converted from NetCDF to Geotiff format for ingestion. Since this was a multi band monthly aggregated image and I wanted to allow the user to slice by time frame, the image bands were seperated as individual images and the overall results are image collections with date range information attached.

### Projects Elc Gdp (`docs/projects/elc_gdp.md`)
# Global Electric Consumption revised GDP
In this study, we employed a series of methods, such as a particle swarm optimization-back propagation (PSO-BP) algorithm, to unify the scales of DMSP/OLS and NPP/VIIRS images and obtain continuous 1 km × 1 km gridded nighttime light data during 1992–2019. Subsequently, from a revised real growth perspective, we employed a top-down method to calculate global 1 km × 1 km gridded revised real GDP and electricity consumption during 1992–2019 based on our calibrated nighttime light data.
Gridded population and nighttime light data are the most popular proxy tools, and have been adopted extensively because of their strong correlation with economic output and electricity use. Finally the authors note that although nighttime light data as a single indicator may ignore factors such as value added or reduced by forestry or desertification, it is still an effective proxy for calibrating economic growth.You can [read the paper here](https://www.nature.com/articles/s41597-022-01322-5)

### Projects Electric Grid (`docs/projects/electric_grid.md`)
# Facebook Electrical Distribution Grid Maps
Facebook has produced a model to help map global medium voltage (MV) grid infrastructure, i.e. the distribution lines which connect high-voltage transmission infrastructure to consumer-serving low-voltage distribution. The data found here are model outputs for six select African countries: Malawi, Nigeria, Uganda, DRC, Cote D’Ivoire, and Zambia. The grid maps are produced using a new methodology that employs various publicly-available datasets (night time satellite imagery, roads, political boundaries, etc) to predict the location of existing MV grid infrastructure. The model documentation and code are also available , so data scientists and planners globally can replicate the model to expand model coverage to other countries where this data is not already available.
Building Electrical Grid Maps begins by taking monthly images from the VIIRS satellite, and creating a composite. We then apply a custom image processing filter to remove background and reflected light, and identify locations that consistently demonstrate night-time lighting. These then serve as a proxy for the existence of grid electricity. Using known electrical grids as templates based on data available from energydata.info, we employ a custom algorithm to connect the communities and infer grid paths based on their likelihood to follow roads, avoid water, and follow the shortest paths possible. You can find the model code and documentation here: https://github.com/facebookresearch/many-to-many-dijkstra
Note: current model accuracy is approximately 70% when compared to existing ground-truthed data. Accuracy can be further improved by integrating other locally-relevant information into the model and running it again.

### Projects Emc Built (`docs/projects/emc_built.md`)
# Copernicus EMC-BUILT Global Built-up Surface R2025A
The Copernicus Exposure Mapping Component (EMC) Built-up product (EMC-BUILT R2025A) provides high-resolution global information on built-up surfaces, non-residential structures, and vegetation within built-up areas for the reference year 2022. This dataset represents the first operational Copernicus production of built-up information based on Sentinel-2 data and deep learning architecture, ensuring continuity with previous Global Human Settlement Layer (GHSL) products while introducing major methodological innovations. The dataset is produced by the European Commission's Joint Research Centre (JRC) as part of the Copernicus Emergency Management Service (CEMS) to support crisis management, disaster risk reduction, urban planning, and sustainable development monitoring.
The production employs a modified U-Net convolutional neural network (CNN) trained on Sentinel-2 imagery with comprehensive geospatial covariates including spectral metrics, temporal harmonics, and building footprints from multiple open sources (OpenStreetMap, Microsoft Building Footprints, Google Open Buildings). The dataset provides three core products at multiple resolutions (10m, 100m, 1000m in World Mollweide projection, and 3/30 arc-seconds in WGS84): total built-up surface, non-residential built-up surface, and greenness fraction within the built-up domain. All products follow an open and free data access policy aligned with the Copernicus programme principles.
#### Methodology Overview
The EMC-BUILT production workflow consists of six main steps:
1. **Pre-processing**: Computation of spectral and temporal metrics from all Sentinel-2 Level-1C scenes for 2022, including harmonic coefficients and percentile composites
2. **Reference Data Collection**: Compilation of global building footprint data from multiple open sources (OSM, Microsoft, Google)
3. **Model Training**: Development of a modified U-Net CNN to map Sentinel-2 metrics to built-up surfaces
4. **Prediction**: Application of trained models across all Sentinel-2 tiles with ensemble predictions
5. **Post-processing**: Ensemble averaging, commission error correction using auxiliary indices (NDWI), and value rescaling
6. **Mosaicking and Reprojection**: Assembly and reprojection to global grids in Mollweide and WGS84
The greenness layer is derived from median NDVI values with a 300m buffer around built-up areas to capture vegetation in and around settlements.
!!! info
EMC-BUILT and GHSL R2023 are incompatible data streams. Direct temporal comparisons or change detection between these releases are not supported due to substantial methodological differences.

### Projects Energy Farms (`docs/projects/energy_farms.md`)
# Harmonised global datasets of wind and solar farm locations and power
Energy systems need decarbonisation in order to limit global warming to within safe limits. While global land planners are promising more of the planet’s limited space to wind and solar photovoltaic, there is little information on where current infrastructure is located. The majority of recent studies use land suitability for wind and solar, coupled with technical and socioeconomic constraints, as a proxy for actual location data. Here, we address this shortcoming. Using readily accessible OpenStreetMap data we present, to our knowledge, the first global, open-access, harmonised spatial datasets of wind and solar installations. We also include user friendly code to enable users to easily create newer versions of the dataset. Finally, we include first order estimates of power capacities of installations. We anticipate these data will be of widespread interest within global studies of the future potential and trade-offs associated with the global decarbonisation of energy systems.

# EOG Annual VIIRS Night Time Light
???+ note
**This dataset is currently only available to those in the [insiders program](https://gee-community-catalog.org/insiders/)**
A new consistently processed time series of annual global VIIRS nighttime lights has been produced from monthly cloud-free average radiance grids spanning 2012 to 2021 is processed by the Earth Observation Group(EOG). The new methodology (version 2.1) is a modification of the original VNL V1 that is available in the Earth Engine catalogue. Compared to VNL V1, this improved VNL V2.1 version removes ephemeral lights and background noise.
In both methods there is an initial filtering to remove sunlit, moonlit and cloudy pixels, leading to rough composites that contains lights, fires, aurora and background. In the original method, the rough annual composites are made from a full year of nightly DNB data. In the new method, the rough composites are made on monthly increments and then combined to form rough annual composites. Both methods employ outlier removal to discard biomass burning pixels and isolate the background.
In the original method the outlier removal is performed on scattergrams generated for each 15 arc second grid cell, with outliers clipped off from both the high and low radiance sides of the scattergram. The discard of outlier pixels proceeds until the scattergram’s standard deviation stabilizes. The new method uses the twelve-month median radiance to discard high and low radiance outliers, filtering out most fires and isolating the background. Background areas are zeroed out in both methods using the data range (DR) calculated from 3x3 grid cells. In both methods, the DR threshold for background is indexed to cloud-cover levels, with higher DR thresholds in areas having low numbers of cloud-free coverages. In the new method, particular attention is given to setting a single DR threshold for distinguishing lit grid cells from background for each 15 arc second grid cell. This is achieved by setting the DR threshold from a multiyear maximum median and a corresponding multiyear percent cloud-cover grids. The multiyear approach makes it possible to detect lighting present in each 15 arc second grid cell with a single DR threshold across all the years in the series.

### Projects Era5 Heat (`docs/projects/era5_heat.md`)
# ERA5-HEAT Dataset
This dataset provides a complete historical reconstruction for a set of indices representing human thermal stress and discomfort in outdoor
conditions. This dataset, also known as ERA5-HEAT (Human thErmAl comforT) represents the current state-of-the-art for bioclimatology data record
production. The dataset is organized around two main variables: 1) the mean radiant temperature (MRT) and 2) the universal thermal climate index
(UTCI) These variables describe how the human body experiences atmospheric conditions, specifically air temperature, humidity, ventilation and
radiation.
The dataset is computed using the ERA5 reanalysis from the European Centre for Medium-Range Forecasts (ECMWF). ERA5 combines model data with
observations from across the world to provide a globally complete and consistent description of the Earth’s climate and its evolution in recent
decades. ERA5 is regarded as a good proxy for observed atmospheric conditions. Additional external information is available on this [product here](https://cds.climate.copernicus.eu/cdsapp#!/dataset/derived-utci-historical?tab=overview).

### Projects Esrilc2020 (`docs/projects/esrilc2020.md`)
# ESRI 2020 Global Land Use Land Cover from Sentinel-2
This layer displays a global map of land use/land cover (LULC). The map is derived from ESA Sentinel-2 imagery at 10m resolution. It is a composite of LULC predictions for 10 classes throughout the year in order to generate a representative snapshot of 2020. This map was produced by a deep learning model trained using over 5 billion hand-labeled Sentinel-2 pixels, sampled from over 20,000 sites distributed across all major biomes of the world.
The underlying deep learning model uses 6 bands of Sentinel-2 surface reflectance data: visible blue, green, red, near infrared, and two shortwave infrared bands. To create the final map, the model is run on multiple dates of imagery throughout the year, and the outputs are composited into a final representative map of 2020.
Processing platform
Sentinel-2 L2A/B data was accessed via Microsoft’s Planetary Computer and scaled using Microsoft Azure Batch.

### Projects Et0 (`docs/projects/et0.md`)
# Global Reference Evapotranspiration Layers
The Global Aridity Index (Global-Aridity_ET0) and Global Reference Evapotranspiration (Global-ET0) Version 3 dataset provides high-resolution (30 arc-seconds) global raster climate data for the 1970-2000 period, related to evapotranspiration processes and rainfall deficit for potential vegetative growth, based upon the implementation of a Penman Monteith Evapotranspiration equation for reference crop. The dataset follows the development and is based upon the [WorldClim 2.1](https://www.worldclim.org/data/worldclim21.html) at 30 arc seconds or ~ 1km at the equator. You can read the [paper here](https://www.nature.com/articles/s41597-022-01493-1).
Potential Evapo-Transpiration (PET) is a measure of the ability of the atmosphere to remove water through Evapo-Transpiration (ET) processes. Among several equations to estimate PET, a FAO application of the Penman-Monteith equation (Allen et al. 1998), here referred as FAOPM, is currently widely considered as a standard method (Walter et al. 2000). The FAO introduced the definition of PET as the ET of a reference crop (ET0) under optimal conditions, having the characteristics of well-watered grass with an assumed height of 12 centimeters, a fixed surface resistance of 70 seconds per meter and an albedo of 0.23 (Allen et al. 1998). The FAO-PM is a predominately physically based approach, which can be used globally because it does not require estimations of additional site-specific parameters. However, a major drawback of the FAO-PM method is its relatively high need for specific data for a variety of parameters
(i.e. windspeed, relative humidity, solar radiation, etc.).

# Forest Communities Mapping with AlphaEarth Embeddings
!!! warning "Preprint Dataset"
This dataset is based on a preprint research paper that has not yet been peer reviewed. The methodology, data products, and interpretations may be updated as the paper proceeds through the peer review process. Please cite appropriately and check for updates.
This dataset represents a novel application of deep learning-based geospatial embeddings for ecological mapping, demonstrating how the AlphaEarth Foundations (AEF) model can transform forest community mapping by synthesizing petabytes of multi-source Earth observations into information-rich, 64-dimensional feature spaces. By combining AEF embeddings—which harmonize Sentinel-1/2, Landsat, GEDI, SAR, climate, and numerous other data sources with 22,658 Forest Inventory and Analysis (FIA) plots, this dataset delivers comprehensive forest community maps at 10-meter resolution across the Northeastern and Midwestern United States (U.S. Forest Service Region 9).
The resulting products cover over 65 million hectares of forest across 20 states and include community-constrained species composition for over 50 tree species, plus forest structure metrics (aboveground carbon, total basal area, and stem density). Critically, the AEF embeddings eliminate the need for manual feature engineering that has constrained previous forest mapping approaches, providing globally consistent, highly generalizable predictors that enable both k-nearest neighbor (kNN) imputation for species composition and Random Forest regression for structural attributes. The aboveground carbon estimates outperform four existing national and regional products, demonstrating the transformative potential of geospatial embeddings for large-scale ecological monitoring. You can read the [preprint here](https://ssrn.com/abstract=5936862) for additional details and download the [data here](https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/DTFKCM)

#### Dataset Preprocessing for Earth Engine
The FCM10R9 dataset consists of four main image collections representing different forest attributes. All products were generated at 10-m resolution and masked to forested areas using ESA WorldCover 2021. Species-specific basal area maps were created through kNN imputation, while plot-level metrics were generated using Random Forest regression. The dataset is available through both Harvard Dataverse and Google Earth Engine. The datasets are provided per state and species and merged into collections for easy access and include metadata for easy filtering.
**Metadata Properties:**
All images include the following properties:
- `spatial_resolution`: 10
- `product`: "FCM10R9"
- `version`: "R9"
- `state`: Two-letter state code (e.g., "MA", "NY")
- `metric`: Metric type (e.g., "AGC", "BA", "SD")
- `unit`: Measurement unit (e.g., "Mg/Ha", "m2/Ha", "Trees/Ha")
Species images additionally include:
- `species_code`: Four-letter species code (e.g., "ACRU", "QURU")
- `species_scientific_name`: Scientific name (e.g., "*Acer rubrum*")
- `species_common_name`: Common name (e.g., "Red maple")
