The antipodes of any place on the Earth is the point on the Earth's surface which is diametrically opposite to it. The origin/zero point of this system is located in the Gulf of Guinea about 625 km (390 mi) south of Tema, Ghana. The combination of these two components specifies the position of any location on the surface of the Earth. ![]() The antipodal meridian of Greenwich is both 180°W and 180☎. The meridian of the British Royal Observatory in Greenwich ( London, England) is the international Prime Meridian, which determines the proper Eastern and Western Hemispheres. All meridians are halves of great ellipses, which converge at the north and south poles. The longitude of a point on the Earth's surface is the angle east or west from a reference meridian to another meridian that passes through that point. The north pole is 90°N the south pole is 90°S. The 0° parallel of latitude is designated the equator, the fundamental plane of all geographic coordinate systems, which divides the globe into Northern and Southern Hemispheres. Lines joining points of the same latitude are called parallels. ![]() The latitude of a point on the Earth's surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth.
