A Decade of Geospatial Advancements

As the 25th edition of Intergeo rapidly approaches, Wim van Wegen reflects on his own anniversary: a decade in the geospatial business and attendance at ten consecutive Intergeo events. Huge advancements in 3D mobile laser scanning, unmanned aerial vehicles and total stations are just some examples of the innovative nature of our industry. So what will the future bring? This year’s edition in Stuttgart marks the 25th anniversary of Intergeo. My own personal Intergeo debut was back in 2010, in the city of Cologne, so this is an anniversary year for me too: it will my 10th time attending the... (read more)

3D is the New Normal in Switzerland

Mapless Topographic Products Are the Future
Switzerland is unique in that it is still the only country to have switched entirely to 3D for its national object-oriented topographic database. As users increasingly discover the advantages in terms of new workflows and services, nobody regrets leaving the 2D era behind. According to Swisstopo, the extra dimension creates no extra costs – only extra benefits. It took the Swiss Federal Office of Topography (Swisstopo) ten years to build an object-oriented topographic database in 3D, with the last objects having been completed in 2019. “Nothing is excluded now; everything you can think of is available in 3D. Even the... (read more)

UAV Maps New Zealand Beach to Create Detailed 3D Model

A landslide on Clifton Beach, New Zealand, earlier this year injured two Korean tourists when they were washed out to sea. Following this event, the beach was closed while Hastings District Council undertook a risk assessment. The Surveying Company was contracted to provide data collected by an unmanned aerial vehicle (UAV or 'drone') to assist the council in making public safety decisions regarding access to the Cape. To map the cliff faces they used a combination of RTK GPS and a PPK GPS unit mounted to their UAV. Initially the surveyors concentrated on assessing the main rockfall where the tourists...

Velodyne Lidar Sensors Power Kaarta Mobile Mapping Solutions

Velodyne Lidar recently announced that Kaarta has included Velodyne’s smart, powerful Lidar technology in Kaarta’s new Stencil 2-32 ground surface mapping solution. Equipped with Velodyne Lidar, Stencil 2-32 accurately scans ground-level surfaces, mapping items such as kerbs, manholes, signs, poles and other features at a fraction of the cost of traditional mobile mapping systems. The Stencil platform helps enable city planning for infrastructure improvements as well as parking and traffic management. The 3D data generated by Stencil 2-32 can be utilized for a range of applications including BIM modelling, geospatial data analytics, and cataloging tools. For example, Allvision uses Stencil...

GeoCue Launches Lidar/Imagery Fusion Sensor

GeoCue has unveiled its new True View line of unmanned aerial vehicle (UAV or 'drone') sensors in Nashville, Tennessee, USA. True View sensors offer surveyors an innovative Lidar and dual oblique mapping camera configuration integrated in a single lightweight payload for use on commercial drone platforms. True View allows for fast and easy automated generation of true 3D colourized point clouds, oblique imagery and orthophotos from a single flight. The first sensor of the product line, the True View 410, was displayed at the reveal along with full workflow processing in the companion True View Evo processing software. The True View...

LidarUSA Introduces Long-endurance Multicopter Lidar Solution

LidarUSA has announced the integration of its UAV-scanning systems with the Harris Aerial H4/H6 Hybrid multicopters. As surveyors and mappers experience growth, they take on ever-larger projects, making longer flight times increasingly important. The Harris Hybrid can provide such flights, with Lidar and industrial-grade cameras allowing for far greater coverage in a single flight. “The beauty of the Harris Hybrid is that the pilot continues to enjoy the flexibility of a multicopter, availability of fuel and relatively compact packaging at an affordable price,” says Jeff Fagerman, CEO of LidarUSA. “While it is louder than an all-electric system, for particularly large,...

Virtual Surveyor Puts Emphasis on Lidar Elevation in UAV Mapping Software

Virtual Surveyor has enhanced the Lidar elevation data handling capabilities in Version 6.4 of its unmanned aerial vehicle (UAV or 'drone') surveying and mapping software. A new function enables Virtual Surveyor users to select specific feature classes from classified Lidar point clouds before converting the point cloud into 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 the company in Belgium. Virtual Surveyor, which has doubled its user base in one year, is popular... (read more)
