Small, browser-ready Earth observation projects for IRIS. Each project lives in its own folder and contains exactly two Cloud Optimized GeoTIFF samples. Every folder follows the same layout: 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. See each project folder for source details and the applicable Copernicus Sentinel Data Terms and Conditions.
