LiangXu,

You should use gdalinfo on the subdataset name to find out what coordinate
information GDAL has available, if any.  GDAL does support multi-band
subdatasets though there have been occations when it gets confused about
which dimension is the bands dimension.

Andrey Kiselev is the author of the HDF driver in GDAL and you might want to
consult with him if you need to know particular details.  In the meantime
I would encourage you to experiment a bit.

Best regards,
