The problem
During a flood, the question that matters isn't where the water is — it's which places can still be reached.
The build
Fused Sentinel-1 SAR imagery (which sees through cloud) with OpenStreetMap road networks to map reachable areas during flooding for communities in Assam.
The result
IEEE GRSS hackathon winner, Team Climate Catalyst.
