*SSL4EO-EU-Forest* assembles an additional downstream task (85 GB) for binary semantic segmentation of forest land cover as follows:

- `images/` sub-directory: It curates 16K spatial patches (264x264 pixels) of Sentinel-2 L2A imagery (`UInt16` GeoTIFF, 12 bands upsampled to 10m pixel resolution) over European forests. Each geolocation contains up to four Sentinel-2 timestamps from all seasons (winter, spring, summer, fall) of year 2018. The cloud cover in each scene is below 10%.

- Data of a geolocation are placed in numbered sub-directories (e.g. `0017618`) of `images/` and `masks/`, respectively. Each of those for the `images/` directory contains four directories indicating the four seasons as per convention by Sentinel-2. For example, `20180520T094031_20180520T094033_T35VMH` denotes the sensing start time as approx. May 20, 2018 at 9.41am UTC (spring scene) for geolocation defined by tile ID `T35VMH` (which the patch was cropped from).
