BlueSky and Infoterra announce London Aerial Survey

BlueSky International Ltd. and Infoterra Ltd. have announced a new high-resolution aerial photographic survey of London. The survey will cover the whole of Greater London, some 1600 square kilometres. Flying will unusually take place during the winter months of 2005-6 which will mean that there will be no leaves on the trees affording un-obscured views of the built environment and road network. With each image pixel representing 10cm on the ground the new imagery will provide highly accurate and up-to-date detail of the capital. Traditionally UK aerial photography is flown during the summer months with trees in full leaf but for uses such as road network analysis, planning and construction projects, winter flying was considered more appropriate as it reveals more ground detail. The survey will form part of the joint venture national imagery layer being promoted by BlueSky and Infoterra.

13 of London’s 33 boroughs have already placed orders for the new imagery, which will form a seamless digital map of their territory and its immediate environs, within their GIS. Local Authorities and other London organisations can benefit from real-life views provided by this imagery, which will reveal much more about what is actually on the ground than conventional mapping. Bluesky and Infoterra will use the latest digital camera technology to achieve a full photogrammetric survey of the Greater London area accurate enough to ascertain building heights and to create 3D models, as well as providing details such as road markings, street furniture, individual trees and much more.
