The Sentinel-1 Observed Flood Extent identifies the pixels covered by floodwater.
Pixels being usually under water (identified based on the monthly “Sentinel-1 Reference Water Mask” are not part of the Sentinel-1 Observed Flood Extent. This mask is obtained using the ensemble flood mapping algorithm described in section 0.
During the NRT operation, the acquisition month of the Sentinel-1 scene is retrieved from the“Sentinel-1 Metadata” and the corresponding monthly “Sentinel-1 Reference Water Mask” is cropped to the extent of the processed Sentinel-1 scene. The Sentinel-1 Observed Flood Extent values are described below.
