Clarify Class 0 and Withheld Flagging

The current text regarding Point Classification can be confusing with regard to points flagged as withheld. This revision clarifies the requirement.

Status of this revision: Published in Lidar Base Specification 2020 rev. A

Current requirements in LBS v.2.1:
Point Classification
  • All points that fall within the minimum classification scheme (table 5) and not flagged as withheld shall be properly classified.

  • No points in the classified LAS deliverable may remain assigned to Class 0.

Approved change:
Point Classification
  • All points that fall within the minimum classification scheme (table 5) and not flagged as withheld shall be properly classified.

  • No points in the classified LAS deliverable may remain assigned to Class 0, unless these points are flagged as withheld.
