Hi guys,
the GEOID settings should be improved a lot and better documentation should be written on that matter.
Also, it must be get clearer how the transformations takes place and when the new settings are applied,
I am using Photoscan more than 5 years and still there are a lot of dark corners on these matters...
The user should be able to set different datums (Horizontal & Vertical) for the cameras and the control points and maybe different project datum (the datum of the results...).
A scenario that I found tricky to solve was:
1) Camera with onboard RTK GNSS saving geotags in WGS84/ellipsoidal heights (sensefly eBee plus - SODA)
2) GCPs measured for assessment of the results in EPSG:2100 and EGM2008
3) results needed in the GCPs datum
