Reword mandatory zero classification for synthetic LiDAR #86

Closed pchilds closed 3 years ago

pchilds commented 5 years ago

The specification for classification states:

This field represents the “class” attributes of a point. If a point has never been classified, this byte must be set to zero

As it stands this states that the synthetic, key-point and withheld flags would also be zeroed. I believe this should say "the lowest five bits must be set to zero" as a point never being classified should not preclude it being synthetically derived.

That makes sense to me. I'll queue this for the next update.
