FloodMap™ – flood maps worldwide

Visualise and assess your flood risk

Our flood maps are used by insurers, government agencies, property developers and emergency response services to visualise, assess and understand flood risk.

Modelled using our tried-and-tested flood simulation software and high-quality topographical and flood-source data, we can generate flood maps or flood risk data sets for most countries around the world, and have many countries available off-the-shelf.

Flexible resolution and licensing options

To make our flood maps as flexible and affordable as possible, you can choose varying resolutions, specific regions, or request that only some sources of risk are included. Not everyone needs a precise high-resolution flood map that provide building-level information, as our Gold/Platinum-level data does.

Delivered as flood maps or flood risk datasets

Flood maps can be supplied as pdfs, or delivered as GIS layers or flat files that can be integrated into your systems. We have yet to encounter a system that we cannot integrate our data into.

FloodMap™ levels

The table below shows our three different FloodMap™ levels and the key technical differences between them. Some of our maps combine data from different levels, if there are gaps in available LiDAR topographical data, for example.
