antipodes
the meridian through greenwich (inside greenwich park), england, called the prime meridian, was set at zero degrees of longitude, while other meridians were defined by the angle at the center of the earth between where it and the prime meridian cross the equator. as there are 360 degrees in a circle, the meridian on the opposite side of the earth from greenwich, the antimeridian, forms the other half of a circle with the one through greenwich, and is at 180° longitude near the international date line (with land mass and island deviations for boundary reasons). the meridians from west of greenwich (0°) to the antimeridian (180°) define the western hemisphere and the meridians from east of greenwich (0°) to the antimeridian (180°) define the eastern hemisphere. most maps show the lines of longitude.
meridian (geography)
longitude (, ), is a geographic coordinate that specifies the east–west position of a point on the earth's surface, or the surface of a celestial body. it is an angular measurement, usually expressed in degrees and denoted by the greek letter lambda (λ). meridians (lines running from pole to pole) connect points with the same longitude. by convention, one of these, the prime meridian, which passes through the royal observatory, greenwich, england, was allocated the position of 0° longitude. the longitude of other places is measured as the angle east or west from the prime meridian, ranging from 0° at the prime meridian to +180° eastward and −180° westward. specifically, it is the angle between a plane through the prime meridian and a plane through both poles and the location in question. (this forms a right-handed coordinate system with the -axis (right hand thumb) pointing from the earth's center toward the north pole and the -axis (right hand index finger) extending from the earth's center through the equator at the prime meridian.)
