Hi Markus,

Yes; it looks like the same issue.

When I googled for the issue, I came across an older different ticket for the 
same "failed to load datum shift file” error but I didn’t see that one.

Greetings,

Just FYI - I imported an image into it’s own location with this command:

r.in.gdal  input=m_4511664.jp2 output=m_4511664 location=m_4511664

In the new location:
g.region rast= m_4511664; v.in.region output=bounds

When I tried re-projecting the from the created location, I got this error:

WARNING: pj_transform() failed: failed to load datum shift file
ERROR: Unable to re-project vector map  from


The cause of the error was this line in the PROJ_INFO file in the location 
created by r.in.gdal (first command shown in this email):

 nadgrids: @null

After removing that line, reprojection works.


Probably it is this ticket?

The error is also described in this ticket, but the issue seems to be 
the difficulty handling the 'nadgrids: @null' hack GDAL uses (IIUC).


See also [1].

Maybe we can create a workaround for this specific issue in v./r.proj ?
