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.

Hi there, this reply won’t be helpful to you but it might be to someone else. What I have found works in the past in this case is to use the point cloud on raster setter to set the geoid z value
