# 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).
