- Pinpoint, particular person property-level evaluation for improved danger analysis.
- Hazard, vulnerability, and information updates.
- Deep dives into excessive windspeed and course, humidity, and different important ambiance components that immediately affect wildfire habits.
- A mess of property-specific traits permitting danger evaluation on the most granular stage.
Cotality innovation gained’t cease with PRID, both. Via ongoing developments to this mannequin, the group will proceed to strategically help a resilient California.
