A queryable spatial index over the JRC/Copernicus CEMS-EFAS Satellite-Derived Flood Depth Maps (Europe, 2015–2024): one Cloud-Optimized GeoTIFF maps each ~90 m pixel to the historic flood events that touched it, plus a Parquet dictionary and per-event metadata; so tools can find which floods hit a location without downloading the depth rasters. Built with the euroflood Python library. Source © JRC/Copernicus EMS, licensed CC-BY-4.0.
