Re: XML Coordinates list



Hi Stephen,

If I use the NcML tab in JAVA NetCDF (2.2) Tools and turn Coordinates ON, I
can get an XML dump describing the 80km CONUS NAM, (as described below).


Is there a command line equivalent of this?

The NcML web page (http://www.unidata.ucar.edu/software/netcdf/ncml/) describes a number of ways to dump the NcML for a dataset: 1) Tools UI, 2) using the netCDF-Java API, 3) netCDF-Java NcDump, and 4) netCDF C library ncdump, version 3.6.1 or later. I would guess that the Coordinates ON option is not supported by the last option. Also, not sure how to specify the Coordinates info in option 3.


How should I include this information for use in an enhanced catalog?

Do you mean how should it be encoded in an enhanced catalog? Or what is the best way to get this information into an enhanced catalog?


Also, is it the variable information you want to include in an enhanced catalog or the coordinate information?

Thanks,
