It combines static effects leading to<br /> &lt;ol style=&quot;list-style-type:lower-roman&quot;&gt;<br /> &lt;li&gt;no-sensitivity in flood mapping&lt;/li&gt;<br /> &lt;li&gt;water-look-alikes&lt;/li&gt;<br /> &lt;li&gt;strong topography&lt;/li&gt;<br /> &lt;li&gt;radar shadows&lt;/li&gt;<br /> &lt;/ol&gt;<br /> <br /> For its generation, we implement the methods proposed '''in section 1''', following the identified problems of SAR-based flood mapping. &lt;br&gt;<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.<br /> |-<br /> |Screenshot<br /> |[[File:GFMEXmap.png|1000px|thumb|centre|]]<br /> |-<br /> |style=&quot;background-color: grey;&quot;| Properties<br /> |style=&quot;background-color: grey;&quot;| <br /> |-<br /> |Available variables<br /> |Exclusion Mask<br /> |-<br /> |Available accumulations<br /> |<br /> |-<br /> |Available interpolation algorithms<br /> |<br /> |-<br /> |Available filters<br /> |<br /> |-<br /> |Spatial aggregations<br /> |-<br /> |}<br /> <br /> <br /> ----<br /> [[User Guide | [Home]]] - [[Observations| [Observations]]]</div>
