Flood inundation & damage mapping
Cloud-penetrating radar maps flood extent while the event is still unfolding — then depth models, population overlays, and pre/post crop comparisons turn extent into relief-grade damage intelligence.
- Works through cloud cover
- Extent within 48–72 hours
- Polygon-level damage evidence
Benefits
What flood inundation & damage mapping unlocks
Short-term optimization
- See full flood extent days before field reports consolidate
- Target rescue and relief using depth and settlement overlays
- Assess crop damage objectively for compensation and claims
Long-term impact
- Event-by-event flood history for every block and village
- Defensible records for disaster-relief audits
- Risk-zonation inputs for planning and insurance
Approach & methodology
How the analytics work
We are transparent about data sources, models, and limits — so you can trust what you act on.
- Data sources
- C-band radar imagery (cloud-independent, ~6-day revisit) with optical pre-event baselines and elevation models.
- Approach
- Radar water classification with threshold and learning-based segmentation; depth estimation from terrain; damage via pre/post change against land-use layers.
- Update cadence
- Event-triggered acquisitions during flood season; fortnightly monitoring for high-risk basins.
- Limitations
- Radar revisit gaps can miss short flash-flood peaks; dense urban cores need careful interpretation.
Deliverables
Expected outputs
- GIS-ready data layers (GeoJSON / KML / SHP / GeoTIFF)
- Decision-ready PDF report with interpretation
- Interactive smart map with time-series view
