- Description
- Classified Point Cloud - AAM uses proprietary ground classification routines in TerraScan to remove any non-ground points and generate an accurate ground surface. Once the ground routine has been completed a manual quality control routine is done using aerial imagery, hill shades, cross-sections, and profiles within the TerraSolid software suite. After this QC step, a peer review and supervisor manual inspection are completed on a percentage of the classified tiles based on the project size and variability of the terrain. Concurrent imagery has been orthorectified and used to colourise the point cloud with RGB values. Overlap Point Flag - Class 12: ’Overlap’ was not used in this project. All points were classified into classes requested and flagged with the Overlap bit flag (Bit 3) in addition to being classified. Geometrically unreliable points near the extreme edge of the swath were classified into class 1, flagged with the Withheld bit flag (Bit 2) and not included in further processing.

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.

- Additional Adjustments
- The survey was adjusted to State Survey Control Marks supplied by the Surveyor General of Victoria
- Environmental Conditions
- LiDAR was captured under standard conditions suited for LiDAR survey with requirements for concurrent aerial photography being a secondary consideration.
