Lidar

Lidar, or Light Detection and Ranging surveying, is a measuring system that uses light. It is widely used in archaeology, forestry, geography, geology, seismology, remote sensing and contour mapping and is spreading to many more geomatics applications. The market for laser scanning is growing strongly as more efficient and cost-effective ways of processing Lidar data create new possibilities in a range of different fields, including construction and engineering, industrial facilities, topographical applications and cultural heritage. GIM International is closely monitoring these developments and will continually keep you updated on the innovations in this ever-changing market through this dedicated Lidar page. Whether you are interested in latest articles and news on Lidar in general or in specific topics like Lidar Survey and Mobile Lidar, you will find it here!
