Only the latest version of Proj (version 9.x) supports transformation (3D -heights!) between the norwegian Nautical Sea Chart Zero (EPSG:9672 and EPSG:9883) and NN2000 (EPSG:5941, EPSG:5942, EPSG:5973 etc.), but also between Nautical Chart Zero and ellipsoidal heights. This does provide a number of advantages, including the possibility of seamless transformation of z-values between sea and land data in Norway. (E.g. from EPSG:5973 to EPSG:9883)

 

FME currently uses PROJ version 7 in the PROJReprosjector- Are there any plans to upgrade to version 9?

 

Do you have any other suggestions on how to transform data in FME from EPSG:5973 to EPSG:9883?

 

Thank you.

Don't know if it will work and if it does it is definitely not the prettiest solution, but could you install Proj 9.x locally and then use it from the PythonCaller?

Hello @hermann​ 

I'm pleased to let you know PROJ has been upgraded to 9.1.0 in FME 2023.0. While 2023.0 is not currently available as a beta download, we anticipate 2023.0 betas should be publicly available in the coming weeks.
