The intersection of lines of reference, usually expressed in degrees/minutes/seconds of latitude and longitude, used to determine or report position or location.
(1) An ordered set of values that specify a location. (2) Linear or angular quantities, or both, which designate the position of a point in relation to a given reference frame. There are two general divisions of coordinates used in surveying: polar coordinates and rectangular coordinates. These can each be subdivided into three classes: plane coordinates, spherical coordinates, and space coordinates. (3) An ordered pair (triple) of numbers that when graphed in a particular system of coordinates represents the relative location of a particular feature. Coordinates are the primary spatial identifiers used in the development of computer mapping data bases.
