Thanks Micha. Good to know I¹m on the right course. After the first step: ³g.region vect=States save=ConUS² I can indeed ³zoom to saved region² in the display to view the map. However, g.region region=ConUS shows: projection: 99 (Albers Equal Area) zone: 0 datum: wgs84 ellipsoid: wgs84 north: 1838.08985202 south: 34.12860299 west: -1467.66023444 east: 1403.23869107 nsres: 0.05000031 ewres: 0.04999998 rows: 36079 cols: 57418 cells: 2071584022 Unfortunately, the bounds are all offset from the central axis so I can¹t use the lat. & lon. values for the boundaries as you suggest. (ie west=-120 east=-110) I can overlay a grid and get a good estimate of values that will work to define my regions.
