MMDC Europe (full dataset)

MMDC-EU is a multi-year, multimodal SITS dataset spanning Europe. This dataset is composed of the following data: the Sentinel 2 L2A product (processed with Sen2cor), the Sentinel 1 ascending and descending orbits, ECMWF AGERA5 weather variables, and a digital elevation model (DEM). Although all modalities are not initially available at a 10m resolution, all products are up-sampled on the Sentinel-2 10m spatial grid. Multi-year multimodal SITS were acquired from January 2017 to December 2020.

Specifically, the pre-training dataset gathers data from eighteen S2 tiles. This pre-training dataset is divided into training and validation sets. To build the training dataset, ten smaller non-overlapping ROIs of size (512,512) are randomly selected from each of the twelve training tile. The disjoint validation dataset is composed of the remaining six S2 tiles, from which thirty ROIs of size  (128,128) are randomly drawn. The code utilized to create the multimodal dataset is provided, allowing for potential future expansion : https://src.koda.cnrs.fr/iris.dumeur/openeo_datasets
