Daniel,

You can grab the latest GDAL snapshot from CVS and test it for support
for your datasets. I am not sure that my approach will work in all
possible situations, but it should work in your case. I do not know
other tools suitable for batch processing, it is hard to automatically
process HDF files, because they are designed to be human readable in the
first place and not machine readable. MRT is higly specific tool, so it
is probably the best choice for MODIS processing, though the GDAL driver
tries to be the universal one.

I think that MRT can be used in batch mode, you just need to cgenerate
control file on the fly, something like

for i in *.hdf ; do
	echo INPUT_FILENAME = $i >prm.prm
	echo OUTPUT_FILENAME = `basename $i .hdf`.tif >> prm.prm
...
done


Regards,
Andrey
