Conceptual Consistency
- Comments
- ICSM Level 2+ classification was applied and the data files include RGB imagery point colourisation on all tiles.
Missing Data
- Comments
- LiDAR data was captured and GNSS solutions applied as in following pages. Absolute and relative calibrations were applied to ensure a level surface. This data was then classified using automated and manual processes, culminating in in-house QA in a specialised environment. From here, adjustments were calculated and applied. DEMs were processed using ground point TIN processing and contours using a specially-thinned ground point subset.
