Footprint polygons can be used in building vectorization process. This short tutorial explains the importance of the footprint quality and demonstrates the Check Building Footprint Polygons and other tools in TerraScan to improve it. The same tools can be used to check the building information quality of topographic maps.
List of tools used in this presentation:
- Check Footprint Polygons – Tool for checking polygons before using for 3D building vectorization
- Compute Normal Vectors – Compute and store additional attributes for laser points
- Display Mode – Used to display points by computed normal values
- Define Classes – Alter point weight by class for display adjustment
