r.patch does exactly that, no flags needed.
Markus, A related issue: when I want to reproject raster DEMs from their source location to a common target location r.proj fails because the source's region is outside the target's region. How this can be makes no sense as the target's region is an entire state and the DEMs are 7.5' topographic quads. But, that's what r.proj tells me. I've not found how to resolve this issue. Example: the target location's (OR) default region is: g.region -l north-west corner: long: 125:01:06.208515W lat: 46:54:29.991261N north-east corner: long: 115:30:24.620534W lat: 46:53:20.948674N south-east corner: long: 116:00:36.987691W lat: 40:41:04.56057N south-west corner: long: 124:33:45.521802W lat: 40:42:06.559349N center longitude: 120:16:28.077102W center latitude: 43:53:09.60569N rows: 691017 cols: 724617 g.region -p projection: 99 (unnamed) zone: 0 datum: ** unknown (default: WGS84) ** ellipsoid: grs80 north: 369907.96287773 south: -321108.56796525 west: 2155817.84893823 east: 2880434.93778086 nsres: 0.99999932 ewres: 1.00000012 rows: 691017 cols: 724617 cells: 500722665489 and a source's smaller region (Elwood) is: g.region -l north-west corner: long: 122:22:30.177355W lat: 45:14:59.998015N north-east corner: long: 122:15:00.21557W lat: 45:15:07.129823N south-east corner: long: 122:14:59.838614W lat: 45:14:54.839228N south-west corner: long: 122:22:29.773496W lat: 45:14:47.707842N center longitude: 122:18:45.005157W center latitude: 45:14:57.48019N rows: 415 cols: 10732 g.region -p projection: 99 (unnamed) zone: 0 datum: ** unknown (default: WGS84) ** ellipsoid: grs80 north: 582841.5 south: 581596.5 west: 7719262.5 east: 7751458.5 nsres: 3 ewres: 3 rows: 415 cols: 10732 cells: 4453780 I need to understand why r.proj fails and how I can fix these situations.
