Fathom’s Global Flood Map provides its users with the most robust and comprehensive set of hazard data and flood risk information in the world. Available across all major flood perils: pluvial, fluvial and coastal, it revolutionizes how insurers, financial markets, engineers, corporates and governments can understand and integrate flood hazard and climate change data into their risk operations.
Key features of Fathom’s Global Flood Map
~30-meter resolution globally
1 arcsecond data, based on FABDEM+, our latest complete map of the Earth’s terrain
Downscaled to 10-meter resolution where advanced regional data permits
Climate Dynamics
Fully flexible climate conditioned flood hazard data for any projected combination of future year and climate scenario up to 2100
Inland and coastal
Fluvial, pluvial and coastal flooding – Assess the risk from major types of flood including defended and undefended views
Terrain data
Underpinned by an unparalleled Digital Elevation Model (DEM) combining FABDEM with the best available local LiDAR data
Access
Gain instant on-demand access via the Fathom API and Fathom Portal, or host the data on-premise
Flood layers
Depths for return periods between 5 and 1000 years
Risk Scores (Relative Risk and Risk Category) for each type of flooding
