UGRID, FVCOM, unknown_1d mesh, compliance problem? #50

Closed nbrinks closed 3 years ago

nbrinks commented 3 years ago

I am trying to retrieve the triang from a NetCDF file. (https://noaa-ofs-pds.s3.amazonaws.com/leofs.20210114/nos.leofs.fields.f000.20210114.t00z.nc) but whenever I try to open the file the mesh that is generated is unknown_1d. AFAIK this NetCDF file is an unstructured grid following FVCOM. Is this some sort of compliance issue with the file? Am I doing something wrong? Any help is appreciated. Thanks!

See my example notebook at https://gist.github.com/nbrinks/004d0c96e80619815dcc0a27d0ee6b18

Yep. You did nothing wrong, the data provider needs to add more metadata to make this a ugrid compliant dataset. See both checks in the last cell of the notebook below:

Closing this b/c it is not a problem with gridgeo.
