Hi! -Using exclusively GRASS modules I think you must (1) reproject in another location (with r.proj) and (2) export (with r.out.*). Pay attention to the current region settings (check/set extent and resolution with g.region). -Using gdal utilities you might be able to reproject and export in one step [1] Kind regards, Nikos [1] http://gfoss.blogspot.com/2008/06/gdal-raster-data-tips-and-tricks.html _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
