DESCRIPTION


The r.region program allows the user to manage the boundaries of a raster map. These
boundaries can be set by the user directly and/or set from a region definition file
(stored under the windows directory in the user’s current mapset), a raster or vector map,
or a 3dview file.

The align parameter sets the current resolution equal to that of the named raster map, and
align the boundaries to a row and column edge in the named map. Alignment only moves the
existing boundaries outward to the edges of the next nearest cell in the named raster map
-- not to the named map’s edges. To perform the latter function, use the raster=name
option.

NOTES


After all updates have been applied, the raster map’s resolution settings are recomputed
from the boundaries and the number of rows and columns in the raster map.

The n=value may also be specified as a function of its current value: n=n+value increases
the current northing, while n=n-value decreases it. This is also true for s=value,
e=value, and w=value.

EXAMPLES


Assign absolute coordinates to map:
r.region map=mymap n=220750 s=220000 w=638300 e=639000
Shift map (using offset, here by 100 map units in two directions):
r.region map=mymap n=n+100 e=e+100 w=w+100 s=s+100
