Chris is right - the netcdf driver in gdal was designed to read netcdf data and create netcdf files from other formats, not write complex files.
Anything else is a hack - better to use other tools if you want to combine bands, variables, etc. Etienne On Mon, Jul 23, 2012 at 2:07 PM, Chris Barker <chris.bar...@noaa.gov> wrote: > On Mon, Jul 23, 2012 at 7:50 AM, Anton Korosov <anton.koro...@nersc.no> wrote: > >> how to create a NetCDF file with several variables that have more than two >> dimensions? > > I"m sure you can get this to work, but... > > netcdf has a pretty different data model than GDAL -- I suspect you'll > be fighting that regularly.
