Hello,
I need to read certain pixels from an HDF file (can be HDF4 or HDF5, we
have both) using the FORTRAN interfaces.
The files are quite large (around 40 datasets, each ~44000x2200 pixels)
and I wish to only read a specific number of these pixels. The pixels I
wish to read are reasonably contiguous (a swatch of satellite data) but
are not rectangular or any other regular shape, so I can't just extract
a rectangular hyperslab.
I guess it is possible to read pixel-by-pixel until I have all the data
I need, but that probably isn't very efficient. Any ideas for the best
way to do this?
Cheers,
Simon
