Real-world 3D Height Data Enhances Flood Prediction Modelling
Latest Cities Revealed London LiDAR survey supports insurance industry
The GeoInformation® Group, publishers of Cities Revealed aerial photography (www.citiesrevealed.com), announce today the capture of new LiDAR (Light Detection and Ranging) data for London. This latest survey is the most current height data solution available to the market and can be used to create detailed 3D ground and surface models. It is the ideal solution for the insurance industry to accurately predict flood risk through height and volume analysis and 3D visualisation for the Capital.
LiDAR is an airborne mapping technique that uses a laser to measure the distance between the aircraft and the ground in much the same way that sonar uses sound, or radar uses radio waves; providing a very accurate 3D model of the world. Cities Revealed London LiDAR has been captured at 1m intervals.
LiDAR has revolutionised the acquisition of digital elevation data and has quickly become a de facto method of collecting height and surface information for a myriad of applications and analysis. There is no other method that can collect ground and surface height information as quickly, accurately and as cost-effectively.
Alun Jones, Managing Director of The GeoInformation Group comments, “With a changing global climate and the increasing threat of damage from flood in particular, there is a growing need for more effective and accurate data for land and property risk assessment. The use of digital elevation models, derived from LiDAR surveys, provides a highly accurate basis from which the insurance industry can assess flood risk. The GeoInformation Group have invested in a new LiDAR survey of London to provide this valuable information to the insurance and reassurance market, in order to aid them in making better informed flood risk prediction models.”
With an already comprehensive and current archive LiDAR data is now readily available from Cities Revealed. Metropolitan areas with LiDAR coverage include: London, Manchester, Birmingham, Liverpool, Newcastle, Edinburgh and Glasgow. Cities Revealed will further expand the archive to meet industry demand.

Each month we select a hot topic and a leading figure in the industry to write about it.HAVE WE REALLY LEARNT THE LESSONS FROM LAST YEAR’S FLOODS?
Flooding costs associated with extreme weather, both financial and emotional, have increased considerably over the last decade, and experts have predicted this trend is set to continue.
Paul Livett, Chairman of GroundSure looks into how increasing the use of flood risk information in property transactions can help to ensure both residential and commercial transactions are conducted on a truly informed basis, with buyers being made aware of environmental risks prior to purchase.
Over 2.2 million homes and small businesses in the UK are located in areas considered at risk of flooding, and the Association of British Insurers (ABI) has said that 570,000 of these face a high risk of flooding. The floods in June and July last year left approximately 48,000 households… More…
