Fathom’s data now available in CatNetⓇ

Product launches 15.04.2024

As demand grows within the insurance industry to quantify and evaluate flood risk more accurately, Fathom announces its US Flood Map is now available in CatNet®, Swiss Re’s leading location intelligence platform. 

CatNet®, Swiss Re’s proprietary risk assessment tool, is used by organizations to analyze their exposure to natural catastrophe risk. The integration of Fathom’s independently validated, high-resolution US Flood Map into the tool marks a significant milestone in enhancing CatNet’s® existing flood modeling resources, to supply clients with the highest quality dynamic flood risk assessments.

Fathom’s US Flood Map is the most comprehensive flood map for the United States, offering an unprecedented level of detail and accuracy. Its features include: 

  • ‘Gold standard’ LiDAR coverage for 94% of buildings.
  • Newly available LiDAR for 57% of US land.
  • The estimated influence of all 84,000 dams on extreme flows nationwide; a world-first.
  • The first flood map to cover every river, stream and coastline in the country.


Floods, historically known as a secondary peril, are rapidly becoming a primary concern for re/insurers worldwide with climate change making them larger, less predictable and more expensive. Research by the World Bank indicates that approximately one in five people in the world are exposed to substantial flood risk. With their frequency, size, and costs on the rise, insurers and companies with assets in flood-prone areas require more advanced tools to navigate this evolving threat landscape.

Incorporating US Flood Map into CatNet® enables sophisticated climate-driven present-day flood risk assessment, instead of relying on historical data alone. This integration also enables users to leverage multiple flood risk models simultaneously on a single platform, facilitating more comprehensive risk assessments.

The news marks the first step in integrating Fathom’s award-winning portfolio of flood maps into CatNet®.
