Fathom launches new Global Flood Map – Fathom-Global 3.0

Company updates 27.10.2022

A fundamental change in our global view of flood risk

Today, we launched our new Global Flood Map, Fathom-Global 3.0. For the first time risk professionals can access all perils and climate options.

Unlike most maps that are limited to inland fluvial and pluvial flood data, Fathom-Global 3.0 also models coastal flood risk. In addition, users can access flood maps that draw on scientific data representing the size, width, depth and flow of every river channel in the world, providing unprecedented levels of detail.

Fathom-Global 3.0 enables users to quantify and mitigate flood risk, and understand changes in risk under future climate scenarios. The map is at 30-metre resolution globally and is based on terrain data from FABDEM, Fathom’s latest complete ‘bare earth’ Digital Elevation Map of the Earth’s terrain, enriched with LiDAR data where it is available.

“We launched Fathom in 2013 with an aim to deliver science-driven and fully transparent flood modelling and to accelerate the world’s understanding of flooding on a global scale. Fathom-Global 3.0 is our biggest step yet to making high quality flood hazard data accessible worldwide. It is by far the most robust and comprehensive flood dataset available today” explains Fathom co-founder Dr Andrew Smith.

“Having reliable and sound flood hazard data is fundamental to understanding the exposure and resultant vulnerability of any property, facility and asset. This is especially important for risk professionals across many industries who, until now, have struggled to obtain complete and consistent data across all the countries in which they have business,” Smith continued. 

Fathom’s new Climate Dynamics framework is the only technology on the market that allows users to customise their data to varying regulatory requirements. Users can examine any inland or coastal flood peril for any projected combination of future year and climate scenario or temperature change – bringing to market a new ability to understand flood-related climate change impacts.

Unlike other flood maps which rely primarily on observational data, Fathom-Global 3.0 draws on extensive peer-reviewed academic research and scientific data sources to simulate the behaviour of water across all flood perils.

In another major development, the data is accessible via the new Fathom API. This allows customers who prefer on-demand use to access all spatial data without the need to host files. For customers who wish to bring the dataset in-house or access data via a Fathom partner, Fathom continues to offer a range of flexible data access options.

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.

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 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.

For insurance and reinsurance: Flood hazard data is fundamental to understanding the exposure and resultant vulnerability of any property, facility or asset. This is especially important for insurance and reinsurance professionals who, until now, have struggled to obtain complete and consistent data across all the countries in which they have business.

For banking, advisory and capital markets: Fathom-Global 3.0 will particularly help institutions who are assessing portfolio risk across both data-rich and data-poor areas of the world. Providing a comprehensive picture of flood risk for the first time. Firms will be able to fully understand portfolio flood risk, consider the necessary precautions to mitigate it and answer regulatory, legislative and customer demands for risk management and reporting.

For engineering, government and international development: Reliable and sound flood hazard data is fundamental to understanding the exposure and resultant vulnerability of any potential site, project, infrastructure or asset. This is especially important to engineers working on feasibility, scoping and risk assessment for projects in data scarce regions that need to meet specific requirements over the lifetime of and asset. Fathom-Global 3.0 will prove vital to engineers, governments and international development organisations who are compelled to conduct ever more detailed and precise assessments.
