Hi Simone, I just tried udig and it works (so it should work with geotools
as well). But it didn't work until I set up gdal correctly. But as far as I
understood the imageio-ext-gdal driver it doesn't handle tiff data? Do I
need a gdal driver or do could it help in my case?

As far as I understood the ASTER GDEM license I'm not allowed to
redistribute it. Here is a Link: http://www.gdem.aster.ersdac.or.jp/ but you
have to log in. I will send you an example file as private mail.
