Thinning and refining points

If necessary, you can thin points to remove those that are redundant. You can also refine points that have a high root mean square (RMS). That is, you can opt to run thinning, refinement, or both simultaneously. When you select to have thinning and refinement run simultaneously, thining occurs first with refinement immediately thereafter.

Typically, you run thinning, refinement, or both, after you have run automatic point collection and, as a result, have redundant points in an over-collected region or points that have a high RMS due to poor correlation.

In the Point Thinning and Refinement window, do one of the following:
