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 in https://huggingface.co/datasets/embed2scale/SSL4EO-S12-downstream .

Data Characteristics

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%.
  • masks/ sub-directory: Forest masks (0 = non-tree covered areas, 1 = broadleaved forest, 2 = coniferous forest; Byte GeoTIFF) 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 .
  • 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).
