Raster map to align to
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 allows to set 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
