For a more comprehensive documentation the reader is referred to the GFMS Products Description Document.
The GFMS makes available a full set of NRT flood mapping-related products as listed below:
- S-1 Observed Flood Extent
- S-1 Observed Water Extent
- S-1 Reference Water Mask
- Exclusion Mask
- Uncertainty Values
- Advisory Flags
- Sentinel-1 Metadata
- Sentinel-1 Footprint
- Sentinel-1 Schedule
- Affected Population
- Affected Land Cover
It is worth mentioning that, output layers 1 (observed flood event), 2 (observed water extent), and 3 (reference water mask) are provided in both raster (Geotiff) and vector(shapefile) format.
Output layers 4 (exclusion mask), 5 (uncertainty values), 6 (advisory flags), and 10 (affected population) and the additional proposed 11 (affected landcover) are provided in rasterformat (Geotiff), output layer 8 (Sentinel-1 footprint) in vector format and output layer 9 (Sentinel- 1 schedule) as a KML files.
