In recent years, use of unmanned aerial systems (UASs) has soared as a means for capturing geodata by images and Lidar. However, this does not mean that proven platforms, such as helicopters, have bec...

Basic tools for processing Lidar point clouds, which can be extended depending on needs, provide a flexible platform for service providers and users alike. Here, the authors demonstrate how a publicly...

Until now, most commercially available airborne Lidar systems have operated on one single wavelength, reflecting energy from a pulse which is then used for classification or visualisation. New develop...

Canadian Lidar company Optech originated in 1974 as a spin-off from Allan Carswell’s research at York University in Toronto, where he had initiated one of the first Lidar research programmes. GIM In...

SPAR Europe and European LiDAR Mapping Forum 2014 was held from 8-10 December 2014 in Amsterdam, The Netherlands. The event focused on the acquisition, generation, storage and processing of 3D point c...

For representing terrain heights INSPIRE, which is aimed at creating an EU spatial data infrastructure, has developed specifications for digital terrain models (DTMs). DTMs are preferred as the main s...

This year’s HxGN Live, Hexagon Metrology’s annual user conference, was once again held in Las Vegas, USA, from 2-6 June. Its maxim: ‘Great Stories Start Here’. From a geomatics point of view t...

Since this issue of GIM International is dedicated to Lidar point clouds, it should come as no surprise that it contains an interview with a leading expert on this exciting aspect of the geomatics spe...

Airborne Lidar has become a regular technology for acquiring accurate, consistent and dense point clouds. However, the constraints on specifications, available sensors and aerial platforms are still a...

The longest-standing ‘remote sensing’ technology – photogrammetry – has already been around for 150 years. Indeed, she is a venerable lady in the realm of geodata acquisition, and the founding...
