3D topographic representation of the territory in the form of a point cloud. LiDAR (Light Detection and Ranging) technology allows the terrestrial surface to be represented 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 a multitude of details to be obtained at ground level and surface elements. LiDAR technology quickly, easily and most importantly accurately provides the elevation of ground details and features above the ground, even in dense vegetation. The uses are: creation of a digital terrain model (DTM), creation of contour lines, volume calculation, planning, calculation of tree height, mapping of building roofs, 3D modeling of cities, etc. Source: XEOS Imagerie Inc.This third party metadata element was translated using an automated translation tool (Amazon Translate).
