A cross section through point cloud...
In this part of the point cloud there is a difference between Lidar datum and photogrammetric one of about 0,20/0.30 meters...
Flat surfaces show this singular artefact...similar to some waves..
Why?

You can see two marker used to set reference distance.
This distance was measured from an available ortofoto in a GIS software..
