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.
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.SEE ALSO
