Analysis of lidar and aerial photography by Simon Crutchley and Fiona Small, both of Historic England, has led to the rediscovery of a long-speculated route in Roman times. The suc...
Mounting Lidar on an unmanned airborne vehicle (UAV) is regarded by many as the next geospatial frontier, but gradually the barriers are being overcome. Scientists and Lidar-...
Ron Roth of Leica Geosystems and Marcos Sirota of Sigma Space Corp explain how this technology will bring benefits through faster pulse rates and denser point clouds. Current airbo...
Current airborne Lidar systems, such as the Leica ALS series, capture one million points per second. Increasing the pulse repetition rate is the best way to achieve dense point clo...
Today, automatic matching of overlapping aerial imagery and airborne Lidar are the main geodata technologies for capturing dense point clouds of the Earth’s surface. The samp...

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 res...
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 proc...
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 pre...
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 poi...
Airborne Lidar has become a regular technology for acquiring accurate, consistent and dense point clouds. However, the constraints on specifications, available sensors and aerial p...
Compiled by editors Jie Shan and Charles K. Toth, this newly published book provides a comprehensive and in-depth treatment of Lidar as an accurate, direct method for 3D...
The first commercial airborne Lidar systems appeared on the market in the mid-1990s. This active remote-sensing technology rapidly evolved to become the laser scanners which can to...
Early in 1997 I did research on gaining insight into the error sources of airborne Lidar. As you may have read in the editorial in this issue of GIM International, 1997 was the ye...
This is the second Product Survey on Airborne Lidar Sensors; the last appeared under the title ‘Airborne Laser-scanners’ in our May 2004 issue. Seven companies were willing to co-o...
Optech Incorporated focuses on the development, manufacture and support of advanced, lidar-based survey solutions. Established in 1974 as a privately held, Canadian-owned research...
