I have these ASTER images, in hdf format. I tried to import then with
r.in.gdal, but I get errors:
r.in.gdal input=/home/guano/grassdata/AST_L1B_003_07042001134227_11162003075003.hdf

How can I get then into GRASS?

I still cant have my ASTER imagens on GRASS. I have builted HDF4,
rebuilted GDAL with support for HDF4 and GRASS.
If I try r.in.gdal:
r.in.gdal input=/home/guano/grassdata/AST.L1B.00309052003132740.09242003132138.hdf

Carlos,
if you want to use r.in.gdal, you will have to use the full reference to
a HDF4 subdataset as required by gdal as
HDF4_SDS:subdataset_type:file_name:subdataset_index. You can see that
r.in.aster does so, if you look at its output: it calls gdalwarp with
'HDF4_SDS:ASTER_L1B:"/home/guano/grassdata/AST.L1B.00309052003132740.09242003132138.hdf":2' as input file. You'll have to use something like that too. You can find out how to reference your hdf subdatasets by running gdalinfo on your hdf file (then indeed just give it the filename). It will tell you the full hdf reference and its subdatasets. For more info, see http://www.remotesensing.org/gdal/frmt_hdf4.html.
Vincent.

Try the r.in.aster script. This uses gdalwarp to import and georectify the
aster imagery.

Something is worong with the coordinate system, which is not set in the image.
This is the first lines of gdalinfo:

Carlos,
Your version of GDAL is outdated. Please, grab the most recent version
(you need the CVS snapshot). Everyone who need georeferenced ASTER
should take the GDAL sources from CVS, older code does not work
properly with ASTERs.
Best regards,
Andrey
