This dataset was created as part of the Geo-harmonizer project, with the scope of making open data easier to access. It contains all the flood activations mapped by the Copernicus Emergency Rapid Mapping Service between 2012 and 2020. To obtain these GeoTIFFs, the vector data packages from CEMS were individual downloaded, rasterized and mosaicked per year and season, resampled at 30-m and reprojected to EPSG 3035: ETRS89-extended / LAEA Europe. If no CEMS flood activation was identified in a specific year and season, the raster was not created. The rasters are provided as COG files, type=16Int, the flooded area pixels have value 100, nodata value is 255. To allow an easier and faster search through all 2012 - 2020 CEMS flood activations, we have prepared a point vector layer (geojson) containing one point for each flood activation area of interest with the following attributes attached: CEMS identification number <ems_id>, area of interest defined by CEMS <ems_aoi>, URL link to the CEMS activation <ems_link>, year of the event <year_start>, <year_end> , <season> and the name of the <geo_harmonizer_raster> where the 30m rasterised delimitations of the flooded areas of the corresponding flood activation can be found.
