Quality

Conceptual Consistency

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

Missing Data

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.
