An x and y coordinate used to represent a location in two-dimensional space, for example (6,4).

set of dimensional discrete values describing the location of a point, line, or polygon (area) feature in relation to the common coordinate system of the database.

a set of cartesian coordinates (east-west and north-south distance, or latitude and longitude) describing the two-dimensional location of a point, center of a line or centroid of a polygon, from some known reference datum.

set of Cartesian coordinates describing the two-dimensional location of a point, line, or area (polygon) feature in relation to the common coordinate system of the data base.

An easting and northing in any coordinate system, absolute or relative. Together these two values, usually termed (, ) describe a location in two-dimensional geographic space.
