Description

LiDAR data captured using on-board GPS, IMU and a network of local base stations. Trajectories and laser data corrected initially using the AusGeoid2020 and then adjusted to AHD using local base stations. LiDAR data is classified into multiple ground and non-ground classes. Derivative products are provided from the triangulated surface.
