Custom configurations can be linked to live data feeds to meet specific user needs. It also keeps flood information readily accessible and allows users to get more from their data.


Flood Viewer provides a range of tools to interrogate the data and show different scenarios. You can pan and zoom around the map and switch layers on and off as needed, including  background mapping, property points, defence lines or aerial photography.

Using industry standard web browser technology, Flood Viewer avoids the need to purchase expensive GIS software.

The software provides an integrated solution for sharing flood extents online, streamlining the way you collaborate with colleagues and clients. The setup tool in Flood Modeller helps you create a project, uploads your outputs to the Flood Viewer server and provides you with a secure web link to share with different stakeholders.
