geographic region - A rectangular area (region), stated in the map coordinate system of the GRASS location under which the region is stored, whose sides are parallel to the coordinate axes. A geo- graphic region also has an east-west resolution and a north-south resolution associated with it, which specify the dimensions used by individual cells falling within the region's boundaries.
NOTE: In earlier versions of GRASS, the term "geographic window" was used to denote a geographic region.
