Quality

Conceptual Consistency

ICSM Level 2+ classification was applied and the data files include RGB imagery point colourisation on all tiles. 

Missing Data

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. 

Tidal Conditions

Not Applicable to this block (or within +/- 2hrs of low tide if a coastal blocks)
