Quote “Fathom’s data are super granular, which is something that our customers value a lot. You need that granularity to really understand how a flood will impact an asset.”

Elliot Christou CReDo CReDo Technical Lead

Quote Fathom’s methods of peer review give it a different kind of credibility. We knew that they were the experts and the right people to work with. The team was really enthusiastic about supporting our innovation goals and very generous with their time explaining how to use and interpret the data.

Model features

01

Terrain data

Global Terrain Data - FABDEM+

Fathom’s flood maps are underpinned by the best globally available terrain dataset for flood modelling – FABDEM+. The true global bare-earth terrain data combines FABDEM with high-quality laser altimeter (LiDAR) data gathered as recently as 2023.

Fathom’s team has been at the forefront of building market leading Global Terrain Data since 2017, when we first published the methodology for MERIT DEM.

02

Multi-peril

Multi-peril

With sub-perils explicitly modelled to build a comprehensive understanding of the impact of different flood sub perils on different assets.

03

Climate data

In a rapidly evolving climate landscape, relying solely on historical records can lead to substantial mis-estimates of hazard. Fathom’s products incorporate data from relevant climate models, meaning that Fathom’s technology accounts for the growing impact of a non-stationary climate.

04

Return periods

Return periods - Flood hazard data Fathom

All of Fathom’s products simulate flood events for 10 return periods ranging from the 1-in-5 to the 1-in-1000 year flood. This enables users to understand the implications of a wider range of flood events and allows for a better understanding of event frequencies.

05

Flood depths

Fathom flood depths

Flood depths and extents are critical to understanding the impact and severity of flooding for all three flood sub perils.

06

Risk Scores

Fathom’s flood data are now also available as Risk Scores. Offering a simple yet powerful way to compare the flood risk for assets across your portfolio. Available in two forms, Relative Risk and Risk Category, the metrics are designed to deliver a consistent method of understanding how flood risk varies from one location to another.
