Does anyone have any solid comparisons of results (stockpiles for example), from having a typical fly over with no gcp vs RTK/PPK gcps?
I've seen a lot of discussions but cannot seem to find any side by side results to show the level of difference between.
Obviously we know sites like DD say no GCPs are necessary for relative accuracy, and in my experience they are right to a degree. I've had ~2cm accuracy on 2D objects I've measured in real life vs using DD or P4D (the latter being more accurate). So I'm curious what kind of level of accuracy you can get from 3D volumes without GCPs?
