In this short tutorial, learn how to detect trees from a photogrammetric point cloud using TerraScan and TerraSurvey in MapPowerView. The same workflow can be used for any point cloud, such as UAV or traditional aerial laser scanning. Transform loaded points – Calculate height from ground List Survey – Export tree trunk data into text…
This short tutorial shows the suggested road curb detection method using TerraScan’s Find Curb Along Element tool. This tool creates two 3D line elements following the lower and upper edges of curb stones in a point cloud. It separates the lower and upper edge by a given minimum horizontal distance so the breaklines may be…
