Re: [Geotools-gt2-users] Error when reading NetCDF file (Geotools 13.1)

[Daniele R. <dan...@ge...>]

Dear Gabriella,
that version of GT only supports lon/lat NetCDFs (WGS84
coordinateReferenceSystem).
The latest master version should also support other projections which are
described by gridMapping attributes as part of the CF convention:
http://cfconventions.org/Data/cf-conventions/cf-conventions-1.6/build/cf-conventions.html#appendix-grid-mappings

So I'm not sure your specific dataset will be recognized.
Hope this helps.
Cheers,
Daniele
