There are a wealth of visualisation options in Flood Modeller. The latest version make it easy to visualise data within the main interface – especially with web base map layers. From Flood Modeller, you can also view data in the 3D Viewer or export KML files of flood extents (including time series results) to view in Google Earth.

Flood Viewer was originally developed for flood incident rooms, to make it easier to reliably access vital flood extents and contextual information leading up to and during a flood event. We quickly realised that it could also be a useful tool for anybody to share flood extents, and has been part of Flood Modeller for a number of years. The Flood Viewer setup tool previously allowed you to choose (and set the style of) layers to include in your project, then would automatically download Ordnance Survey Open Data background mapping for anywhere in the UK, creating a self-contained desktop folder that could run offline (although it was built on web technologies and ran in a web browser).

For Flood Modeller version 4.4, we have completely rebuilt Flood Viewer, and it now makes sharing your model outputs quicker and easier than ever.

The user interface has been modernised, but the simple slider (mimicking a real-world gauge board) will be familiar to users of the desktop version of Flood Viewer. The slider offers you an intuitive way of fading between results by simply dragging up and down – quite literally as Flood Viewer is now designed to work well with touch screen devices (such as iPads and other tablets).

Flood Viewer is now an online tool, and the Flood Viewer setup tool in Flood Modeller uploads your data and generates a simple link that you can then easily share with anybody. Background mapping is built in and now works across the globe with no setup required, with three different layers to choose from (including satellite imagery).

You can view an example project here and try it out yourself using Flood Modeller Free and Flood Modeller Pro version 4.4. You will find the setup tool under Map Tools > Flood Viewer.


This is just the first step for Flood Viewer online, and there are big things to come. It is still in beta, so your feedback can shape its future development by helping us understand how well it works, how you use it and the features you would like to see in the future – submit an idea on the Ideas Lab or fill in our quick survey.
