|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
<ol style="list-style-type:lower-roman">
  <li>no-sensitivity in flood mapping</li>
  <li>water-look-alikes</li>
  <li>strong topography</li>
  <li>radar shadows</li>
</ol>

For its generation, we implement the methods proposed '''in section 1''', following the identified problems of SAR-based flood mapping. <br>
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.
