Hi Even,
Thanks for the pointer to this resource, and for working to support this
important functionality.
Would it make sense to add the -a_coord_epoch option to gdal_edit.py, so users
can directly update the GeoTiff header for a dataset with known epoch?

Hi Even and Javier,
For the special case of a DEM, would it make more sense to specify the units
with a vertical CRS? This approach would define the LENGTHUNIT and the
associated vertical datum.
Example for EPSG:4979:
AXIS["ellipsoidal height (h)",up,
ORDER[3],
