How Snowflake's AI Identifies Buildings Facing Flood Risk

Sustainabilitymag · · 795 words · By Lucy Potter

Snowflake and Ordnance Survey have developed an AI-driven model to identify flood-vulnerable buildings in England by integrating mapping, deprivation, and flood risk data. The analysis highlights that many at-risk buildings are older structures located in deprived areas, providing recommendations for more granular, data-driven policymaking.
