The term meridiangenerally refers to any line that runs pole to pole, on the surface of a sphere. Figure 2a (left): The Earth's coordinate system, latitude and longitude. The central axis runs through the North and South poles. Figure 2b (right): The pole-to-pole lines along the surface are lines of longitude.
A geographic coordinate system is a coordinate system that enables every location on the Earth to be specified by a set of numbers or letters, or symbols.The coordinates are often chosen such that one of the numbers represents vertical position, and two or three of the numbers represent horizontal position.he latitude (abbreviation: Lat., Ï, or phi) 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 (or close to) the center of the Earth.
