Bluesky’s 3D Aerial Laser Maps Inform BIM Projects
Leicestershire, UK, June 9, 2016— – 3D models produced from aircraft mounted lasers are being used by survey company Greenhatch Group to help inform a range of Building Information Modelling (BIM) projects. Downloaded from aerial mapping company Bluesky’s online Mapshop (www.blueskymapsop.com), the highly accurate and detailed models are utilised within the group’s BIM software from Autodesk, providing real world context to measured survey and laser scanned data. The Bluesky height (LiDAR) data also gives Greenhatch up to date and accurate information for areas that may be inaccessible or otherwise out of bounds.
“The Bluesky photogrammetric models are invaluable when integrated alongside models produced on the ground from either traditional survey techniques or, more recently, terrestrial laser scanners,” commented Stuart Chadwick, BIM Manager at Derby based Greenhatch Group. “The data provides context for buildings we have surveyed and modelled, and gives us data for areas we have not been able to access.”
Greenhatch Group is a well-established survey practice with nearly thirty years’ experience in completing topographical, building, engineering and utility surveys across a range of industry sectors. Greenhatch utilises the very latest surveying technology to ensure highly efficient workflows whilst ensuring data quality and accuracy for its high profile clients, including English Heritage and Historic Scotland, for example. Greenhatch Group was also an early adopter of BIM, defined as a process involving the generation and management of digital representations of physical and functional characteristics of places, and described by the UK Government as ‘the first truly global digital construction technology’.
The datasets used by Greenhatch Group are purchased from Bluesky’s online Mapshop, which offers complete nationwide coverage of aerial photography from multiple epochs, 3D models (Digital Terrain and Surface Models DTM / DSM), LiDAR data, Thermal Mapping and the National Tree Map. Visitors to the Bluesky Mapshop can also download free of charge geological, land cover and flood maps, as well as places of interest, census areas and collections of themed data such as farming, marine and habitats.
“The service we received from Bluesky, both online – via the Mapshop and offline – via more traditional channels, has been first class,” continued Chadwick. “They are prompt in response to any queries or requests, very competitive and the turn around on orders is fast.”
Bluesky is a specialist in aerial survey including aerial photography, LiDAR and thermal data using the very latest survey technology, including two UltraCam Eagles and an Orion M300 LiDAR system. An internationally recognised leader with projects extending around the globe, Bluesky is proud to work with prestigious organisations such as Google, the BBC and Government Agencies.
Bluesky has unrivalled expertise in the creation of seamless, digital aerial photography and maintains national “off the shelf” coverage of aerial photography, DTM and DSM through an on-going three-year update programme. By purchasing a world first sensor for the simultaneous capture of LiDAR, Thermal and Aerial Photography data, Bluesky is in the enviable position of being able to provide customers with unique and cost effective solutions.
Bluesky is leading the way in developing innovative solutions for environmental applications, including the UK’s first National Tree Map (NTM), solar mapping and citywide ‘heat loss’ maps and is currently developing noise and air quality mapping products.
Greenhatch Group can trace its origins back over 30 years when the practice began life as a partnership agreement typically providing services to the quarrying and mining industries.
By 1988 the practice had firmly established itself within the development sector of the industry and, with a steady expansion of technical equipment and qualified staff, Greenhatch Group was suitably formed.
The practice has continued to grow and evolve over the last 10 years, allowing the expansion into many new exciting disciplines and sources of industry. This expansion has also allowed Greenhatch Group to utilise and evolve its technical resources over time to a point where the company now utilises the very latest and highest quality survey instruments available in the market.
Based on the success and reputation built up over the last 30 years, Greenhatch Group has been able to maintain a strong and economically viable position during such difficult times, and is now confidently emerging as one of the principle pioneers and market leaders within the challenging surveying sector.
