Copernicus EMS Global Flood Monitoring (GFM)

Continuous near-real-time global monitoring product that processes incoming Sentinel-1 IW GRD SAR scenes with three flood-mapping algorithms and an ensemble rule. It publishes 20 m Observed Flood Extent and Observed Water Extent rasters, scene footprint/metadata, and related quality layers. Flood extent is a model-assisted satellite classification: class 1 is flood, class 0 is no flood, and 255 is no data; normally-water pixels are removed using the monthly reference-water mask. REST, WMS-T, STAC, map viewers, portal downloads, raster/vector downloads, and archive ordering are delivery modes of this one product.
