Flood detection Sentinel-1

Flood detection Sentinel-1 detects flood areas from a pair of Sentinel-1 SAR images.
The AI of this block is trained to detect flood areas while ignoring other types of water surface, which is difficult for conventional methods to perform, by seeing changes between 2 SAR images from 2 different times at the same scene. This algorithm uses Res-Unet to detect flood regions.

Due to technical restrictions of Sentinel-1 L1 GRD (SAFE) data block, currently, our block can only be used for flood detection with imagery in Europe.

Supported Workflows:

• Sentinel-1 L1 GRD (SAFE) -> SNAP Polarimetric Processing Sentinel-1 -> Flood detection Sentinel-1
