Implementation of new laser scanning technology from Hexagon

Mapping and geo services Solutions

Airborne laser scans are reaching new heights in efforts to create effective and accurate digital contour models. For example, Denmark has the Digital Elevation Model from the Agency for Data Supply and Efficiency (SDFE), which is based on Lidar scanning with four points per , but the development of laser scanning technology is advancing rapidly, and COWI Mapping is testing and using the latest technology in the shape of Hexagon’s Single Photon Lidar (SPL100).

To support this technological development, COWI launched a pilot project covering Copenhagen and the Great Belt bridge to gain greater knowledge and understanding of possible new applications of SPL technology.

The SPL scanner uses a new technology in which a laser pulse is split into 100 smaller beams. The system can then measure six million points per second, which is around 10 times faster than traditional Lidar scanners. With a resolution of 10-100 points per  and accuracy to 5-10 centimetres, it presents scanned objects in unprecedented detail.
