This layer displays an *x*/*y* grid in meters for the WGS 84 / Antarctic Polar Stereographic projection (EPSG:3031). This coordinate system shows the planar distance in meters from the map projection origin (90°S) in both the *x* and *y* dimensions. The distances are displayed in exponential notation: e.g. 2.5e+06, which is the same as 2.5x10^{6} or 2,500,000 meters. *x* values above the South Pole on the map are positive while those below it are negative. Similarly, *y* values to the right of the South Pole on the map are positive while those to the left are negative. The maximum extent (min *x*, min *y*, max *x*, max *y*) for the Southern Hemisphere is approximately: -12,500,000 m; -12,500,000 m; 12,500,000 m; 12,500,000 m.
