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!
Lidar technology is synonymous with 3D point clouds. To get the most out of 3D point cloud data, it is necessary to step back and continually consider the newest trends in Lidar technology and how the...
A recent study created crop type maps using Lidar, Sentinel-2 and aerial data along with several machine learning classification algorithms for differentiating four crop types in an intensively cultiv...
Recent technological developments have made aerial surveying more exciting than ever. For imagery, ground resolutions of 2cm can now be reached, whereas for Lidar, pulse frequencies of 4GHz and point ...
What will be the future of Lidar? To quote Abraham Lincoln: “The most reliable way to predict the future is to create it”. So what is currently being created in the geospatial market? This article...
A few obstacles are making the usage of Lidar data in archaeology look exotic and perhaps even threatening, according to archaeologist Jošt Hobič from Slovenia, even though Lidar is almost a must wh...
Various multibeam Lidar sensors are suited for mobile mapping. Read this article to learn more about their features and productivity. In mobile mapping, geospatial data is acquired by one or more came...
