Layer name	Exclusion Mask (GFM)
Tag	Flood
Folder	Eo Satellite
Source	Exclusion-Mask
Description	The Exclusion Mask indicates the pixel locations where the SAR data could not deliver the necessary information for a robust flood delineation. It combines static effects leading to no-sensitivity in flood mapping water-look-alikes strong topography radar shadows For its generation, we implement the methods proposed in section 1, following the identified problems of SAR-based flood mapping. The parameter database stores for all locations on pixel basis the areas excluded by the four effect groups, with the radar shadow layer per local Sentinel-1 orbit configurations (up to six per location). During NRT operation, the relative orbit is determined from the S-1 metadata, and the respective Exclusion Mask layers are subset to the extent of the processed Sentinel-1 scene and form a single binary mask for exclusion areas. The Exclusion Mask layer values are described below.
