It seems exceedingly odd to me that to read attributes
from swath datafields, you have to stop what you are doing
and open a new scientific dataset operation, convert
the datafield name to a scientific dataset index, then
parse that for information you need. Too weird!

Anyway, I plan to write an article about this and
incorporate this into my ncdf_browser tool, but who
knows when that will happen. In the interim, I have
put a very preliminary piece of code that parses
HDF-EOS swath data here:

It might give you some ideas.

Cheers,

David
