[GRASS-user] Re: r.region for intersection with vector map?

[Helmut Kudrnovsky]

g.region and r.region are different tools:

g.region - Manages the boundary definitions for the geographic region. 
(http://grass.osgeo.org/grass64/manuals/html64_user/g.region.html)

r.region - Sets the boundary definitions for a raster map. 
(http://grass.osgeo.org/grass64/manuals/html64_user/r.region.html)

g.region sets the extent of the mapset (i.e. for raster calculations), but
r.region defines the extent of the whole raster map.

IMHO g.region is the choice ...
