3D topographic representation of the territory in the form of a point cloud. LiDAR (Light Detection and Ranging) technology makes it possible to represent the earth's surface topographically in three dimensions thanks to a laser system mounted on board an aircraft. The very large number of 3D points recorded (up to 400,000 per second) allows for a multitude of details on the ground and surface elements. LiDAR technology quickly, easily, and most importantly accurately provides elevation of ground detail and above-ground features, even in the presence of dense vegetation. The uses are: creation of a digital terrain model (DTM), creation of contour curves, volume calculation, planning, tree height calculation, mapping of building roofs, 3D modeling of cities, etc. Source: XEOS Imaging Inc.This third party metadata element was translated using an automated translation tool (Amazon Translate).
