A reference datum (mathematical model) is a known and constant surface which is used to describe the location of unknown points on the earth. Since reference datums can have different radii and different center points, a specific point on the earth can have substantially different coordinates

followed by the northing (latitude). These two letters are the first two characters of a full Georef **coordinate** . Each 15-degree quadrangle is further divided into smaller quadrangles, measuring 1 degree of longitude by 1 degree of latitude. These quadrangles are lettered A to Q (omitting

In mathematics , a spherical **coordinate** system is a **coordinate** system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its inclination angle measured from a fixed zenith direction, and the

The Universal Transverse Mercator ( UTM ) **geographic coordinate** system is a grid-based method of specifying locations on the surface of the Earth that is a practical application of a 2-dimensional Cartesian **coordinate** system . It is a horizontal position representation , i.e. it is used

The equatorial **coordinate** system is a widely-used method of mapping celestial objects. It functions by projecting the Earth 's **geographic** poles and equator onto the celestial sphere . The projection of the Earth's equator onto the celestial sphere is called the celestial equator . Similarly
