[geotk] NetCDF Coverage Resampling Issue

[Aaron Braeckel]

Hello,

I am currently doing the following (with SNAPSHOT):

     ImageCoverageReader reader = new ImageCoverageReader();
     reader.setInput( TestUtil.readFile( 
"data/GTG_20090721_v_220000_l_0003600.grb" ) );
     CoordinateReferenceSystem targetCRS = CRS.decode( "EPSG:4326" );
     GridCoverage cvg = reader.read( 0, null );
     Coverage resultCvg = Operations.DEFAULT.resample( cvg, targetCRS, 
cvg.getGridGeometry(), Interpolation.getInstance( 
Interpolation.INTERP_NEAREST ) );
     System.out.println( "Resampled to "+resultCvg);
     reader.dispose();

The call to read() is successful, but when I call resample() I get the 
following Exception:

java.lang.UnsupportedOperationException: Not supported yet.

Is there another method for resampling that I should be using, or 
perhaps is there a component of the NetCDF coverage logic that is not 
yet implemented?

Thanks,
Aaron
