Grid alternative for gllmsl_2022.tif
is not picked up
#4212
Comments
Don't you need the environment variable PROJ_NETWORK=ON ? |
If that was the case I would expect everything to work once the grid was projsync'ed. Also, it is quite clearly trying to access the networks since the error message is that it can't find the grid on the CDN. $ PROJ_NETWORK=ON projinfo EPSG:10566 -k operation -o PROJ [9:57:53]
PROJ string:
Error when exporting to PROJ string: Unimplemented GLLMSL(2022) height to GVR2016 height (1)

Grid gllmsl_2022.tif needed but not found on the system. I think something is happening in the way grid-alternatives are used. The transformation is from one vertical CRS to another so the code probably takes a different path than for the more common case of geoid model transformation. |
Ok. I think I know the reason. The method code 1129 is new, and it is not considered in the c++ code. Is this output enough?

This is what I expect, yes. Looks good! |
When inspecting the transformation from GLLMSL to GVR2016 (EPSG:10566) PROJ tries to use the grid file that is registered with the EPSG (
gllmsl_2022.tif
) and not the PROJ-data alternative (dk_sdfi_gllmsl.2022.tif
) that is available through the CDN. This results in errors both when creating the PROJ string and when trying to lookup the grid on cdn.proj.org. I suspect the latter causes the first problem.dk_sdfi_gllmsl_2022.tif
is available to download:... and having secured the file doesn't resolve the issue above (same error as above but without the WKT):
