UAVs vs MAVs

James Eddy, technical director of Bluesky International and Industrial Associate at the University of Leicester explores the growing phenomena of Unmanned Aerial Vehicles in the UK and discusses the potential impact on the aerial mapping, surveying and GIS sectors. For many years unmanned aircraft were flown by model aircraft enthusiasts. Basic models cost less than a hundred pounds with more upmarket systems for a thousand or more. Now unmanned aircraft (UAs), unmanned aerial vehicles (UAVs), unmanned aerial systems (UASs), remotely piloted aircraft (RPAs), drones – whatever term is in favour this week, are increasingly used for professional applications for data...

Topcon Announces Advanced Bentley Integration for Aerial Photogrammetry Processing

Topcon Positioning Group has introduced the new cloud-based photogrammetry processing powered by Bentley ContextCapture to its MAGNET Collage Web web-based service for the publication, sharing and analysis of reality capture data. The integration allows MAGNET Collage Web users who share and collaborate with scanning and mesh datasets to now process and add unmanned aerial vehicle (UAV or 'drone') photos directly to the MAGNET Collage 3D environment. The built-in Bentley ContextCapture Cloud Processing Service enables operators to upload UAV imagery direct-to-web without the need for high-end hardware requirements or IT constraints. Sharing UAV imagery projects “Operators with photos taken by any UAV will easily use the... (read more)

Increasing Compatibility with UAVs for Precise Mapping

Effigis Geo Solutions (Effigis), a Canadian innovation company that designs, implements and uses geospatial solutions, has launched a new version of EZSurv, the GNSS post-processing software of its flagship OnPOZ suite of software. The release will especially please users of unmanned aerial vehicles (UAVs or 'drones'), with a new UAV image position interpolation module that spares them the trouble of manipulating files. Never before has the process been so short and free of errors – from PPK software to image analysis. The new release now enables users to easily set and save drone configuration and to import Exif image files... (read more)

Experimenting with Low-cost UAVs

The use of Unmanned Aerial Vehicles (UAVs) as serious remote sensing platforms is a growing trend. They are already used in fields such as archaeology, construction, disaster relief, and the oil and gas industry. Sandy Avery and Bruce Gittins argue their ability to be deployed and produce results quickly, requiring only a small team to operate, enables their use in hardtoreach places. Though the financial and technical cost of using UAVs is constantly dropping, there are still high entrance barriers to their use. Many purposebuilt survey drones cost in excess of tens of thousands of pounds and require a significant... (read more)

GeoInformation Group Imagery Helps Map London’s Olympic Legacy

The GeoInformation Group, publishers of mapping and geospatial information products, has supplied stunning UAV aerial imagery of three London 2012 venues owned and managed by Lee Valley Regional Park Authority as part of its maintenance programme. A lightweight Unmanned Aerial Vehicle (UAV) was used to carry out the survey of the Authority’s sporting venues in Queen Elizabeth Olympic Park – Lee Valley Hockey and Tennis Centre and Lee Valley VeloPark – and Lee Valley White Water Centre situated in Hertfordshire, captured at a resolution between 2-5cm per pixel and an area totalling 4km2. Utilising a UAV offered a considerable advantage... (read more)

Virtual Surveyor Enhances Lidar Point Cloud Handling

Virtual Surveyor has enhanced the Lidar elevation data handling capabilities in version 6.4 of its drone surveying and mapping software. The function enables users to select specific feature classes from classified Lidar point clouds before converting the point cloud to a surface terrain. “The latest upgrades in Virtual Surveyor 6.4 are designed to meet the needs of UAV users who are increasingly equipping their drones with Lidar systems,” said Tom Op ‘t Eyndt, CEO of Virtual Surveyor nv in Belgium. Virtual Surveyor bridges the gap between UAV photogrammetric processing applications and engineering design packages. The software generates an interactive onscreen... (read more)
