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
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
Underpinned by an unparalleled Digital Elevation Model (DEM) combining FABDEM with the best available local LiDAR data
Gain instant on-demand access via the Fathom API and Fathom Portal, or host the data on-premise
Depths for return periods between 5 and 1000 years
Risk Scores (Relative Risk and Risk Category) for each type of flooding
Quote Fathom provide a first-rate product and service based upon cutting-edge research and methodologies, which are both robust and transparent. Their flood data sets are global, consistent and high calibre. Most importantly, Fathom is a responsive and collaborative firm who consistently deliver.
Quote Highly knowledgeable presenters with genuine enthusiasm for the work they are doing. A product that can provide global impact in relation to an issue that is extremely high cost, and in a way that can be done efficiently and at scale.
Quote Climate Engine and Fathom have been in partnership for some time and our work with BMO’s Climate Institute is an example of how cutting edge flood modeling plays a key role in helping the bank and their clients mitigate risks associated with the physical impacts of climate change.
Quote Fathom’s flood hazard and risk data products are critical to assessing risks to Microsoft’s cloud infrastructure. In this way, their data impacts the delivery of services relied on by the 400 million global users of Office 365, Outlook.com and OneDrive, and the 48 million members of Xbox.
Quote Fathom’s most recent release – Fathom-Global 3.0 – provides flood maps for anywhere in the world, and at improved levels of detail, providing information to help decision makers better manage their future flood risk by considering climate change and the associated uncertainty.
Accessing Global Flood Map
Fathom’s API is a cloud-based solution for data provision that enables users to access Fathom data on-demand directly.
Fathom’s Portal is an interactive platform that enables users to host, view and analyze data, without the need for an in-house platform.
Fathom’s products can be provided directly as a set of GeoTIFF files and hosted on premise.
Fathom data is available through a range of partners.
The evolution of Fathom’s Global Flood Map
The most comprehensive global view of flood available at the time, Fathom launched its first flood hazard dataset in 2015.
Built on 30 years of published scientific research, it used an early iteration of our global terrain data. We knew that floodplain topography and small flow pathways were poorly defined in some areas and that we could significantly improve on this in future releases.
Groundbreaking flood hazard data:
- Terrain data: custom-processed SRTM
- Discharge estimation: Global RFFA
- River channels: HydroSHEDS+
- Efficient Fathom hydraulics models
- Fathom model automation framework.
The second iteration of Fathom-Global featured major enhancements. Better representation of river Channels and the ability to produce plausible event footprints were groundbreaking advances.
Our research programme was already pointing the way to even more significant developments to come, especially in our understanding of terrain and river channels.
Major leap in our understanding flood:
- MERIT-DEM terrain dataset
- River channels: MERIT-Hydro
- Plausible event footprints.
A step change in risk professionals’ ability to understand flooding at the global scale.
Coupling the latest topography and hydrography datasets with cutting-edge hydraulic modelling. Our latest terrain data, the first global digital elevation model with forest and buildings removed at a ~30-meter resolution and employing the most advanced representation of river channels available, including estimations of location, size and depth.
State of the art in flood data science:
- Fluvial, pluvial and coastal. The first complete global view of flood hazard
- Climate dynamics. Maps across time periods, warming levels and emissions scenarios
- API. On demand access to all of our spatial data
- 100% of river channels modelled.
