Re: HDF_SD_ADDDATA problem

Thanks, Liam (nice book, by the way).

I haven't yet investigated this, but I'd hope that the IDL routines
are smart enough to decompress before opening the files! Actually I'm
pretty sure they do - I can read the SDS data fine using IDL. But
you're right, writing may be a different story. I'll check it out.

So LAADS MODIS HDFs are HDF4, not HDF5? That's interesting.

Thanks again,
Alex.
