Please post a snippet of the output or check it yourself of v.db.select huss_monavg_2038_395_875 just to be sure that you got the data actually in which you want to be in. Furthermore, .... map extent: | N: 70:15:29.96521N S: 19:27:00.387268N | | E: 35:43:20.669862W W: 157:42:49.097902W | ... computational (current) region extent; north: 70:15:29.96521N south: 69N west: 120W east: 110W nsres: 0:15:05.993042 ewres: 0:20 The "south" value of the computational region does not quite cover the map (intentionally?). Likeweise east and west. (also the pixels are non-square). Perhaps you want to first use (set resolution as appropriate): g.region vect=huss_monavg_2038_395_875 res=0:20 -a to better fit the computational region to the map, then run v.surf.idw. hope this helps, Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
