Hi Yada, If you have a raster map with your area of interest you can use r.mask ... r.mapcalc "DEM_clip=DEM"
or g.region rast=mask_file g.region res=DEFINE DESIRED RESOLUTION r.mapcalc "DEM_clip=DEM" I hope this helps. milton 2011/7/27 Yada Elisabeth <[email protected]> > > > Dear GRASS users, > I download a DEM file( SRTM geotiff) that I opened in GRASS 6.4.1 > One problem I am facing is that I want to extract a part (my area of > interest) of this DEM > I don't know how to proceed > > Yada > Thank You in advance! > > > _______________________________________________ > grass-user mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/grass-user > >
