Conceptual Consistency
- Comments
- ICSM Level 2+ classification was applied and the data files include RGB imagery point colourisation on all tiles.
Missing Data
- Comments
- The LiDAR files are full data tiles (no null space) and the extent and coverage is common with the other datasets in this project.
