There is a lidar data source of digital elevation model of Germany.
- The spec of the lidar data is:
- Horizontal CRS: EPSG 25832
- Vertical DATUM: EPSG 7837
- I have anther DEM whose vertical datum is WGS84 Earth Gravitational Model (EGM 96) geoid.
How can I transform my DEM to make it have the same vertical datum as EPSG:7837. I don't have ground control points. Is it possible to do the transformation without GCP?
