Description

LiDAR data captured using onboard GPS, IMU and network of ground basestations. Trajectories and laser data corrected initially using the AusGeoid09 and then adjusted to AHD using local PSMs. LiDAR data is classified into multiple ground and non-ground classes. Project model key points classified from Ground class automatically; Vegetation (high, medium and low) classified automatically; Bridges classified manually. Ground points are selected from the laser point cloud through iteratively building a triangulated surface model. The building size gives the starting surface point density and the iteration angle determines how close a point has to be to the surface to be included. Ground point thinning is an iterative process similar to ground point classification.
