Description

Ellipsoid ALS data was imported into 'TerraScan' and corrected for the DSE supplied geoid model. Ellipsoid LiDAR data is classified into multiple ground and non-ground classes and split into two folders, non-ground and ground. Ground points are classified and adjusted to ground control points. Vegetation, buildings and bridges were then classified.
