Katrin,
I don't know if gdalwarp will clip your image, check the man page at
http://www.gdal.org/gdalwarp.html
You might consider gdal_translate first to clip the area you want, then
gdalwarp for the reprojection. Use the "-projwin" option to select the
X-Y coordinates of the upper left and lower right corners, and you'll
get a section of the original.
I'd recomend you clip the image before reprojecting so you will be
running gdalwarp in a smaller file
Cheers

THanks Daniel. Since I'm already using gdalwarp, can it be also used to only
reproject a small piece of the image?
Thanks
Best regards,

Check out the gdal_translate utility
http://www.gdal.org/gdal_translate.html
Actualli, it's not a grass tool but grass relies heavily on gdal tools
for raster import so chances are you have that program installed. Just
open a terminal and type gdal_translate. Use the options -projwin to
clip your image to the desired coordinates
Cheers

I'm working with LandCover global datasets and I need to import only an
area
of the dataset since my Region definition will only displays a small
area
(e.g. I'm working with European GLobcover and I only want Belgium and my
Location/Mapset destination region only displays Belgium). How can I
only
import a small region in order to avoid no-needed processing and data
(because If I import and process European dataset it will take much more
time than just belgium).
Thanks
Best regards,
Katrin
