…when these data are input to subsequent analyses?
For example, I select ground returns in the LASd properties filters (not the toolbar). Are only ground returns used as input if I next use the surface contour tool?
Does this apply to surface constraints as well (i.e., if I point to some breaklines files in LASd properties)?
John - this is an excellent question and unfortunately one that can confuse a lot of people.
The answer is "it depends on where you access the LASD to load it into the tool".
