Your projection probably needs a definition in one of the user_projections/ files.
From the Geoserver documentation: User defined NetCDF Coordinate Reference Systems with their custom EPSG need to be provided in user_projections\netcdf.projections.properties file inside your data directory (you have to create that file if missing). I have been pasting projection definitions in user_projections/epsg.properties for now. Here is a link to the documentation regarding Netcdf: https://docs.geoserver.org/stable/en/user/extensions/netcdf/netcdf.html Alex On 8/21/19, Van Der Stelt Frank <[email protected]> wrote: > Hi, Thank you for you answer.
