Using Survey points Just like GCPs
« on: September 29, 2021, 03:25:57 PM »
As a surveyor, I want a more accurate DEM and 3d model,

In standard workflow when we use GCPs, we get a georeferenced and accurate point cloud.

after this, there should be an option to load survey points (topo points with x,y,z value but not marked on the ground like GCPs)

and then recalculate by considering these points X and Y values as it is, and just use vertical Z elevation to get a more accurate point cloud.

If it is already possible then please guide me.

Vertical GCPs can be used already. Just by entering accuracy for the point as 1000/0.01 it will tell Metashape this point is 1cm accurate vertically while XY position is negligible.
