| ## Introduction |
|
|
| The dataset is an add-on to the globally sampled SSL4EO-S12 pre-training dataset (https://doi.org/10.1109/MGRS.2023.3281651) where `v1.1` is available at https://huggingface.co/datasets/embed2scale/SSL4EO-S12-v1.1 with downstream tasks provides https://huggingface.co/datasets/embed2scale/SSL4EO-S12-downstream . |
|
|
| ## Data Characteristics |
|
|
| *SSL4EO-EU-Forest* provides an additional downstream task for binary semantic segmentation of forest land cover as follows: |
| - It curates 16K spatial patches (264x264 pixels) of Sentinel-2 L2A imagery (12 bands upsampled to 10m pixel resolution) over European forests. |
| - Each geolocation contains four Sentinel-2 timestamps from all seasons of year 2018. |
| - The cloud cover in each scene is below 10%. |
| - Binary forest masks have been derived from the 2018 HRL dataset (https://doi.org/10.2909/486f77da-d605-423e-93a9-680760ab6791) available through the Copernicus Land Monitoring Service, cf. https://land.copernicus.eu/en/products/high-resolution-layer-forests-and-tree-cover/dominant-leaf-type-2018-raster-10-m-europe-yearly . |
