No, this was an error in the format page. Rectified now. > Is it possible to create > NetCDF files without having a "prototype" file? Not sure what you mean by a prototype file : a source dataset for CreateCopy() ?

HDF4 can report several subdatasets, which are opened by the HDF4Image driver. To create a HDF4 dataset, you must use Create()/CreateCopy() on the HDF4Image driver. > > Sorry, i am only a beginner in using gdal and any help or pointers to > related documentation is appreciated. You can look at several examples in GDAL python autotest suite : http://trac.osgeo.org/gdal/browser/trunk/autotest/gcore/hdf4_read.py http://trac.osgeo.org/gdal/browser/trunk/autotest/gcore/hdf4_write.py http://trac.osgeo.org/gdal/browser/trunk/autotest/gdrivers/netcdf.py http://trac.osgeo.org/gdal/browser/trunk/autotest/gdrivers/hdf5.py > > Regards, > Mikhail > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
