Pinging @GenericMappingTools/gmt-team. I have uploaded new remote data grids to the test server. These are described here. Note that until we complete the dvc move for test images we have not yet updated the earth_relief files (they are still based off SRTM15+ v2.1 from 2019). Once that is settled I will update those files to 2.3 and add the synbath grid as well. Because of this, if you run all the GMT tests they still all pass since all the DEM images are made using the same DEM as was used in the originals (once we update the DEM we will have ~60 failures...).

In the meantime, I hope you can find time to play a bit with the new datasets. To do so, and not mess up your other remote files, I suggest you do this:

Edit your ConfigUserAdvanced.cmake file (perhaps after updating via the Template) and uncomment this line:

# set (GMT_DATA_SERVER "test")

then rebuild GMT. To preserve your existing cache and server files, simply set them aside via

mv ~/.gmt/server ~/.gmt/server_orig
mv ~/.gmt/cache ~/.gmt/cache_orig

so that you will only use files from the test server. You can now try out making maps with @earth_{gebco,gebcosi,geoid,mag,mag4km,vgg,wdmam} - they all have their own default CPTs that will be downloaded via the cache.

Let me know if you find anything odd. The default CPTs are the ones recommended by the data provider, except Gebco which has not replied. I am therefore using the same geo CPT for all the reliefs.

Once you have finished testing, remove the new directories and rename the old:

rm -f /.gmt/server  ~/.gmt/cache 
mv ~/.gmt/server_orig ~/.gmt/server 
mv ~/.gmt/cache_orig ~/.gmt/cache
