[gdal-dev] modifying HDF4 subdatasets

[Andrea Battisti]

Hi all,


is it possible to modify existing HDF4 subdatasets using the GDAL/HDF4
driver ?


I see that the HDF4 driver should support the creation from scratch, but
given a HDF4 file containing a set of subdatasets, would it be possible
to open one of the subdatasets, (over)writing to it using RasterIO() ?

If not, what is the correct way to modify the content of a sub-dataset?


Thanks in advance for any advise.



Best regards,
