Features of Fathom’s models


Terrain data

Fathom’s models are underpinned by the best globally available terrain datasets for flood modelling. Our global base data are currently being upgraded from MERIT-DEM to a new dataset based called the Forest and Buildings Removed Copernicus DEM (FABDEM).

Our team collaborated in the creation of both ground-breaking datasets. Over certain parts of the globe even higher quality national terrain datasets are available, usually underpinned by laser altimeter data (LiDAR) or photogrammetry derived datasets. Wherever possible these national data are used, including across all of our country specific models.


Damage functions

Differentiate damages between buildings of different characteristics to ensure that you understand the specific risk posed to every link in your production chain.


Exposure data

Fathom’s flood hazard data utilise precise building, population and urban data sets enable our models to understand where flood hazards coincide with human activity and urban development.


Climate data

Climate change illustration flood model

Factor future flood risk into your insurance decisions with models that utilise the latest climate data, rather than relying solely on historical records. Our models for the UK and Japan are built using the latest regional climate data: UKCP18 and D4PDF, under a variety of emissions scenarios so that our models can be tailored to your risk appetite.
