/resources/bridging-the-urban-disaster-gap-with-sar-technology-and-parametric-innovation

SAR technology is making parametric disaster finance more precise by replacing crude rainfall or wind proxies with satellite-confirmed flood footprints and multi-sensor triggers. This Govstar resource explains how cities can reduce basis risk while preserving fast liquidity for emergency operations. Topics include parametric insurance, liquidity gaps, positive and negative basis risk, stepped payouts, return-period mapping, rate-on-line efficiency, SAR flood mapping, depth-duration-area metrics, DEM fusion, urban roughness, NYC subway micro-triggers, Miami wind and flood triggers, New Orleans pump telemetry, Houston bayou models, dual-index triggers, outage data, 911/311 proxies, and parametric capital stacks. **Character count:** ~699 characters.
