OK, this prompted me to release some code I've been sitting on for
awhile.

Check out:

http://michaelgalloy.com/2008/06/27/some-hdf5-helper-routine s.html

The routine MG_H5_GETDATA will do what you want, something like:

IDL> data = mg_h5_getdata(filename, 'group/dataset', bounds='*, *,
0')

where 'group/dataset' is the path inside the HDF5 file to your
dataset.
