Cities Revealed Provides Civil Engineers with Real-world 3D Height Data
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. The Cities Revealed London LiDAR is the ideal solution for Civil Engineers, through height and volume analysis, to accurately plan and visualise engineering projects 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 the extensive development of London, particularly of the Thames Gateway and the 2012 Olympic site there is a growing need for more cost-effective and accurate data for applications specific to civil engineering projects such as volumetric measurement, line of sight measurements and 3D modelling. The use of digital elevation models, derived from LiDAR surveys, provides a highly accurate basis from which the civil engineering industry can produce and analyse the real world from a 3D perspective. The GeoInformation Group has invested in a new LiDAR survey of London to provide this valuable information. It is ideal for all height sensitive applications concerning the Capital.”

Key clients utilising LiDAR data for civil engineering projects, past and present, include BAA Stansted and London Luton Airport. 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…
