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.

NOTE

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.
