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?
Andrea,
GDAL currently only supports writing to the non-HDFEOS dataset type
it creates itself (I think "SDS" datasets).
I haven't tested update in place, but based on a brief review of the
code it seems it ought to work in simple cases.
Best regards,
