October 14, 2009 -- Computer generated 3D visualisations are being used to assess the environmental impact of a proposed redevelopment at one of Britain's industrial landmarks in the north of England. Environmental and engineering consultancy URS Corporation is using digital terrain data from Bluesky to help complete the planning for the major redevelopment project. The Bluesky Digital Surface Model (DSM) will be used to generate a Zone of Visual Influence for Landscape and Visual Impact Assessment.

Due to the location of the proposed development, it was essential that the source data was as up to date as possible and included recently upgraded motorways and intersections. Bluesky was able to offer URS a range of solutions, including NEXTMap height data, a fantastic cost effective product, a LiDAR (Light Detection and Ranging) survey or their own off the shelf 3D model. “It soon became apparent, during early discussions, that Bluesky’s own GeoPerspectives data was the only commercially available height dataset which included the specific section of the upgraded A1(M) that was critical for this project,” commented Ben Stephenson, Environmental Consultant URS Corporation Ltd.

URS selected the data for use within an Environmental Impact Assessment on behalf of one of their clients. An EIA is a multi-stage process that considers the environmental effects of development proposals during demolition, site preparation, construction and operational phases, and proposes ways to eliminate, reduce or mitigate any significant adverse effects on the environment.

Once submitted to the relevant planning authority the EIA documents are critically evaluated, and if necessary, further information is sought from the applicant in order to ensure the authority has sufficiently reliable information to understand the likely environmental effects and proposed mitigation measures before the planning application is determined.

The Bluesky DSM data supplied to URS Corp for this study is part of the GeoPerspectives product range, which offers nationwide coverage of highly accurate, photogrammetrically derived Digital Terrain Models (the earth’s surface excluding buildings and vegetation) and Digital Surface Models (the earth’s surface including buildings and vegetation). Bluesky is also able to provide ultra detailed LiDAR (Light Detection and Ranging) data and services covering the majority of England and Wales including all major urban centres, coastal areas and flood plains.
