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.”

David Mole, Managing Director at Landmark Environment, provides an insight into the opportunities and challenges facing environmental consultants in 2010.
Over the last year there have been numerous events that have impacted upon the environmental consultancy sector. More recently the progress report from the Committee on Climate Change (CCC) issued a clarion call to government to take steps to further reduce carbon emissions, as well as make buildings and industry more efficient. December’s UN Climate Change Summit in Copenhagen has only compounded the sense of urgency for the UK to identify and deliver solutions to mitigate and adapt to climate change.
Looking ahead to 2010, we know the impacts of climate change are already finding their way onto the consultancy agenda. A recent poll among Landmark’s clients found that consultancies expect flood risk assessment to be the biggest growth area for their business during 2010. Carbon footprinting and the energy assessment… More…
