Some premises.
In my work I'm not interested in the georeferencing of the topographic survey and I'm not interested in high precisions.
I need just relative heights and relative distances, even with 10-20 cm error.
Always I got some kind of previous surveys in which large portions of land, unchanged, are measured with great precision.
My idea is to avoid the GCPs and then check or adjust the point cloud based on the pre-existing topographic survey.
Possible ?
