When surface telemetry, cellular towers, and roadways fail during extreme monsoon events, FloodGuard AI processes cloud-penetrating Sentinel-1 SAR imagery and road network topology to locate marooned populations within minutes.
Purpose-built for disaster response commanders, emergency operations centers, and first responder coordinators.
Dual-date Sentinel-1 SAR change detection eliminates cloud obscuration. Computes backscatter drops below -14.5 dB to extract water masks at 10-meter pixel resolution.
Transforms road networks into topological graphs, clips submerged segments against flood polygons, and detects habitations where all dry overland routes are completely cut off.
Ranks isolated communities using weighted multi-criteria decision models. Grounded Gemini AI Copilot explains risk factors while the route engine charts obstacle-free evacuation paths.
End-to-end processing from raw satellite downlink to incident command briefing.
Pre-monsoon cloudbursts triggered severe flooding across 32 districts in Assam, isolating 5.4 million people. FloodGuard AI accurately detects 412.8 km² inundation across Barpeta and Mandia, locating 61,100 cut-off civilians in 5 riverine char communities with zero overland exit corridors.
