NetCDF Output format

This plugin brings in the ability to encode WCS 2.0.1 Multidimensional output as NetCDF files using the Unidata NetCDF Java library.

Installing the GeoServer NetCDF Output format extension

  1. Download the extension from the nightly GeoServer community module builds.

    Warning

    Make sure to match the version of the extension to the version of the GeoServer instance!

  2. Extract the contents of the archive into the WEB-INF/lib directory of the GeoServer installation.

Getting a NetCDF output file

Make sure to specify NetCDF as value of the format parameter within the getCoverage request. As an instance: http://localhost:8080/geoserver/wcs?request=GetCoverage&service=WCS&version=2.0.1&coverageId=it.geosolutions__V&Format=application/x-netcdf...

Current limitations

  • Only WGS84 output CRS is supported
  • Input coverages/slices should share the same bounding box (lon/lat coordinates are the same for the whole ND cube)
  • NetCDF output will be produced only when input coverages come from a StructuredGridCoverage2D reader (This will allows to query the GranuleSource to get the list of granules in order to setup dimensions slices for each sub-coverage)
