Raster map to align to
r.region
NAME
r.region
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.
