[Gdal-dev] The GDAL CF-NetCDF driver seems to lose the geoferencing info on output.

[Rich Signell]

GDAL NetCDF driver folk:

I was excited to see that in the GDAL 1.3.2.0 that I got with FWTOOLS
1.0.6, the CF-style "netcdf" is available as an output format!  (Even
though
http://gdal.maptools.org/formats_list.html doesn't yet list "creation"
for NetCDF, however).

I tried converting a geotiff using:

gdal_translate -of netcdf  SeaWiFS.tif SeaWiFS.nc

and it works fine (but didn't give the usual 0... 10... 20...), but
loses the georeferencing information.  It writes only the pixel values
and not the coordinate variables:

$ ncdump -h SeaWiFS.nc
netcdf SeaWiFS {
dimensions:
        x = 36000 ;
        y = 7000 ;
variables:
        byte Band1(y, x) ;
                Band1:long_name = "GDAL Band Number 1" ;
                Band1:_FillValue = -9999. ;

// global attributes:
                :Conventions = "CF-1.0" ;
                :AREA_OR_POINT = "Area" ;
}


Thanks,
Rich
