Flood Mapping Using Synergic Use of Optical and SAR Imagery

The research aims to provide flood inundation mapping by synergic use of Sentinel-1 (SAR) and Sentinel-2 (optical) satellite imagery. We have applied our algorithm on Kerala region in India, which faced the worst flooding of century in August 2018. The main challenges addressed in the research is to select the suitable parameters for obtaining flooded and non-flooded regions. Major challenge arises due to very high cloud cover in the Sentinel-2 (optical) dataset.
