Surface Water Flood Risk Mapping

In association with Ambiental

The GeoInformation Group, in collaboration with Ambiental, has produced pluvial flood risk maps that show areas of high flood risk.

By combining Cities Revealed's spatial datasets, including the very latest, accurate LiDAR, with Ambiental's flood modelling and expertise, our flood risk mapping solution enables you to predict the depth, duration, velocity and extent of flooding.

Providing a fuller picture of the nature and extent of flood risk can benefit a wide variety of markets including; insurance, government, emergency planning and the utilities to better understand and map flood risk and potential impacts.
