The region's boundaries are given as the northernmost, southernmost, easternmost, and westernmost points that define its extent. The north and south boundaries are commonly called northings, while the east and west boundaries are called eastings.
The region's cell resolution defines the size of the smallest piece of data recognized (imported, analyzed, displayed, stored, etc.) by GRASS programs affected by the current region settings. The north-south and east-west cell resolutions need not be the same, thus allowing non-square data cells to exist.

The fields Default North, Default South, Def West and Def East are the boundaries of the default geographic region that are displayed for reference and cannot be changed. The two GRID RESOLUTION Region fields (east-west, and north-south) are the geographic region's cell resolutions that the user can change. The two GRID RESOLUTION Default fields list the resolutions of the default geographic region; these are displayed for reference and cannot be changed here by the user.
Note: geographic region definition files may be selected from other mapsets as well, if accessible and in the user's mapset search path.
If the user also includes the raster=name option on the command line, zoom=name will set the current region settings to the smallest region encompassing all non-zero data in the named zoom map that fall inside the region stated in the cell header for the named raster map.
w=e-value may be used to set the values of the region's southern and western boundaries, relative to the northern and eastern boundary values.
