The GFM makes available a full set of NRT flood mapping-related products as listed below:
Products | Description | Data Formats |
---|---|---|
1. S-1 Observed Flood Extent | Flooded areas mapped as the difference between S-1 observed water extent and the reference water mask. |
raster (Geotiff) and vector(shapefile) |
2. S-1 Observed Water Extent | Open and calm water mapped using S-1 SAR backscatter intensity. | raster (Geotiff) and vector(shapefile) |
3. S-1 Reference Water Mask | Normal (i.e. permanent, seasonal) water mapped using S-1 SAR backscatter intensity. | raster (Geotiff) and vector(shapefile) |
4. Exclusion Mask | Unclassified areas | raster (Geotiff) |
5. Uncertainty Values | Estimated uncertainty of flood mapping, for all areas outside exclusion mask | raster (Geotiff) |
6. Advisory Flags | Flags indicating potential reduced quality of flood mapping, due to prevailing environmental conditions (e.g. wind, ice, snow, dry soil), or degraded input data quality due |
raster (Geotiff) |
7. Sentinel-1 Metadata | Information on the acquisition parameters of the S-1 data used | KML |
8. Sentinel-1 Footprint | Image boundaries of the S-1 data used | KML |
9. Sentinel-1 Schedule | Next scheduled S-1 data acquisition | KML |
10. Affected Population | Number of people in flooded areas, mapped by a spatial overlay of observed flood extent and gridded population |
raster (Geotiff) |
11. Affected Land Cover | Land cover type flooded | raster (Geotiff) |
More specifics are also available on the dedicated section of the PUM.
