| # IRIS Earth Observation Demos | |
| Small, browser-ready Earth observation projects for [IRIS](https://github.com/asterisk-labs/iris). Each project lives in its own folder and contains exactly two Cloud Optimized GeoTIFF samples. | |
| | Folder | Task | Samples | | |
| | --- | --- | --- | | |
| | `cloud-demo/` | Cloud segmentation | Western Australia and the Alps | | |
| | `flood-mapping/` | Flood extent | Two areas in Sindh, Pakistan | | |
| | `burn-scars/` | Burn scar mapping | Lahaina and Rhodes | | |
| | `land-cover/` | Multi-class land cover | Rotterdam and Mato Grosso | | |
| | `urban-change/` | Urban change, 2018–2025 | New Cairo and Riyadh | | |
| Every folder follows the same layout: | |
| ```text | |
| <project>/ | |
| ├── project.json | |
| ├── images.json | |
| ├── images/<id>/s2.tif | |
| ├── images/<id>/thumbnail.png | |
| ├── images/<id>/metadata.json | |
| └── segmentation/<id>/<user>_mask.tif | |
| ``` | |
| The `segmentation/` paths are populated by IRIS when an authenticated user saves a mask. Project data and annotation results therefore remain together in this repository. Each user needs a Hugging Face token with write access to this dataset. | |
| The newly prepared samples use Copernicus Sentinel-2 Level-2A imagery accessed through [Element 84 Earth Search](https://earth-search.aws.element84.com/v1). See each project folder for source details and the applicable [Copernicus Sentinel Data Terms and Conditions](https://sentinels.copernicus.eu/documents/247904/690755/Sentinel_Data_Legal_Notice). | |
