Geoid import problem. DHHN2016 (GCG2016)

[JFakin]

Hi I want to convert the picture coordinates to geographical CS UTM32 and vertical CS DHHN2016. The problem is that my Geoid for DHHN2016 is defined in ETRS89 and in Metashape I can only chose the Geographic CS for the Geoid that is the same in which it converts. So I can use the Geoid to convert to ETRS89 DHHN2016 but not UTM32 DHHN2016. Does anyone know how to solve this problem?

Geoid file (GCG2016.txt) sample:
55.979166667  3.44375 43.0990
55.979166667  3.45625 999999
55.979166667  3.46875 999999
55.979166667  3.48125 999999

Hi JFakin,

i suggest you define ETRS89/UTM32 Projected CS and from there define the compound CS using the DHHN2016 geoid.. It should work..

Thanks for the Anwser. I did manage to import the Ascii file but the resulting Tiff File is plain white, and in a Test project with 6 GCP i get good 2d accuracy +-3cm but the Height is 4m off. Im speaking of using the GCPs as Controll Points and the Reference was onlly the fotos.  So i assume the Geodi wasnt imported correctly. I followede this instructions: https://agisoft.freshdesk.com/support/solutions/articles/31000148332-how-to-use-height-above-geoid-for-the-coordinate-system

Hi,

it should work. If your GCPs are referred to same Vertical datum then accuracy should be in cm range not m. Maybe double check your GCPs ...
