Modern catastrophe modeling combines geospatial data, weather observations, engineering insights, and historical loss records to estimate extreme-event probability and impact and define reliable triggers. Operationalizing these programs requires near-real-time processing of satellite imagery, weather feeds, exposure datasets, and model outputs. Databricks’ Geospatial Lakehouse unifies those sources on Delta Lake while Spark runs spatial joins and catastrophe modeling pipelines.

## Summary

Parametric insurance pays automatically when objective thresholds—such as wind speed, rainfall, or earthquake magnitude—are met, replacing lengthy loss assessments with event-based payouts. Modern catastrophe modeling combines geospatial data, weather observations, engineering insights, and historical loss records to estimate extreme-event probability and impact and define reliable triggers. Operationalizing these programs requires near-real-time processing of satellite imagery, weather feeds, exposure datasets, and model outputs. Databricks’ Geospatial Lakehouse unifies those sources on Delta Lake while Spark runs spatial joins and catastrophe modeling pipelines. When thresholds are crossed, the system identifies eligible policies, calculates tiered payouts, and surfaces results through dashboards, Lakehouse Apps, and Genie; aerial imagery and multimodal AI can support damage validation and fraud detection, while Unity Catalog governs access and Delta Sharing supports controlled data exchange.

## Context

Traditional indemnity insurance requires verified loss assessments, claims forms, and adjuster involvement, which can delay payouts after catastrophes. Parametric programs instead depend on reliable objective triggers, but they require large volumes of geospatial, environmental, policy, and exposure data to be processed near real time.

## Approach / What changed

The Databricks Geospatial Lakehouse brings satellite imagery, hazard feeds, exposure data, and catastrophe model outputs into Delta Lake. A medallion architecture normalizes hazard data into H3 indices and risk scores, while Spark spatial functions match assets to event footprints and trigger tiers. Dashboards, Lakehouse Apps, Genie, multimodal AI, Unity Catalog, and Delta Sharing support payout operations and governance.

## Takeaways

- Parametric triggers can use measurements from sources such as NOAA and USGS, enabling policies to pay when predefined event thresholds are crossed rather than after traditional claims assessments.
- H3 normalization and Spark SQL spatial functions including ST\_Intersects, ST\_Within, ST\_Buffer, and ST\_Distance support distributed joins across billions of geotagged rows.
- Aerial imagery and multimodal AI can help validate damage and flag potential fraud, while Unity Catalog provides access control and lineage and Delta Sharing enables governed data access without duplicating datasets.
