Visualisation of Vegetation GIS Mapping using LiDAR

Building up from a LiDAR point cloud, an digital elevation model is built from ground points which enables generation of watercourses and contours. Non-Ground laser strikes are then visualised for a highly forested environment in which a number of significant tall trees are located. Those trees exceeding 60 metres in height are then identified by a bright red colour, and ...
