@ nikos : The problem with CSI data is that they are not freely reusable : I
create maps, mostly topographic ones, as hobby for the Wikipedia community
where all media have to be placed under a free license, i.e. which can also
be used for commercial purpose.

@ Marco : These are the srtm and swbd I use but as I wrote, when I try to
launch r.in.srtm or v.in.e00 they crash before opening. I'm very new with
GRASS, is there another way to launch these modules? I'm running
wingrass6.3RC5 : could it be that these modules use the monitor which
doesn't work with this version?

Thanks.
