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 2.5x106 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.
