[gdal-dev] editing NetCDF size using GDAL in C++ code

[Benedetta Onori]

In the creation of a NetCDF I treat subsets as bands.
with gdalinfo I get this:

Subdatasets:
  SUBDATASET_1_NAME=NETCDF:"myfile.nc":Band1
  SUBDATASET_1_DESC=[10000x1] Band1 (64-bit floating-point)
  SUBDATASET_2_NAME=NETCDF:"myfile.nc":Band2
  SUBDATASET_2_DESC=[10000x1] Band2 (64-bit floating-point)
  SUBDATASET_3_NAME=NETCDF:"myfile.nc":Band3
  SUBDATASET_3_DESC=[10000x1] Band3 (64-bit floating-point)
  SUBDATASET_4_NAME=NETCDF:"myfile.nc":Band4
  SUBDATASET_4_DESC=[10000x1] Band4 (64-bit floating-point)
<gdal-dev at lists.osgeo.org>
So it recognizes bands as netcdf subsets, but with Create( ) only one size
for all bands is possible and not different sizes for different
bands-subsets.
