Hi,

On the command line you might use: gdal_translate in.tif out.tif
-a_coord_epoch XXXX.YYY

Hello,
We are trying to create geotiffs from Python and specify an epoch for
a dynamic CRS. Is there a way to do this from python or a command
line utility?
We see the pull request adding CoordinateEpochGeoKey (5120) and expect
I could print the information from gdalinfo if I had an example file.
If we were in C/C++ then we could use libgeotiff and GTIFKeyGet( ).
However we are in Python and we don't see how to write either
the CoordinateEpochGeoKey, or even a generic geokey, into a geotiff.
For reference we looked at the following links:
https://gdal.org/user/coordinate_epoch.html
https://github.com/opengeospatial/geotiff/issues/78
https://github.com/opengeospatial/geotiff/pull/99
https://github.com/OSGeo/libgeotiff/blob/master/libgeotiff/geokeys.inc
Thanks for any help,
Glen and Barry
