The problem
Clouds block optical satellites during floods, so responders lack timely maps of what is underwater.
What to build
Use radar imagery to map flood extent within hours of acquisition and estimate affected villages and roads.
Success looks like
Flood extent that matches reference maps with an agreed overlap score and an automatically produced list of affected settlements.
Suggested technologies
- Sentinel-1 SAR
