A set of two numbers used to determine the position of a point with reference to latitude and longitude. Latitude is the distance north or south from the earth's equator measured through 90 degrees, while longitude is the distance measured east or west from the prime meridian at Greenwich, England, to the meridian passing through a position. Both latitude and longitude are expressed in degrees (or hours), minutes, and seconds.
