The meridian 169° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole, crossing a smaller amount of land than any other line of longitude, and is thus generally used as the cut-off point on a lot of map projections. The 169th meridian west forms a great circle with the 11th meridian east.
