Hello,
I am trying to transform a point cloud with ellipsoidal heights into orthomethic heights (DHHN2016) using the CsmapReprojector. The settings can be seen in the image. For the Geoid Height Grid I need a file in .gdc format. My target system is DHHN2016, for which I have the quasigeoid in various file formats (e.g. JPG, TIFF, GEM, TXT, GSF, GFF, GGF) but not in .gdc.
Is there a website from which I can download the appropriate format or another way?
Thank you very much.
