Hello to all forum members,

I am looking for a solution for searching on a point cloud (*las) of a set with parameters:

1. The height of the set of points does not differ from each other by 0.03 [m], (flat surface) 2. The set creates a rectangular plane with an area of not less than 25-30 [sqr m], (5x5, 4x7 etc.)

Below the workflow on which I stopped.

Thank you for your help.

I agree for negative rule in work-flow, but found "PlanarityFilter" it's tools usefull.

looks like you are attempting to shave of points which are within 0.03 from the top or 0.03 from the bottom of the point cloud.

As max is...max.. the second rule will yield a negative number.

And maybe there are none within this range yuo set?
