This document defines the conceptual schema for the description of referencing by coordinates. It describes the minimum data required to define coordinate reference systems. This document supports the definition of:

— spatial coordinate reference systems where coordinate values do not change with time. The system may:
— be geodetic and apply on a national or regional basis, or
— apply locally such as for a building or construction site, or
— apply locally to an image or image sensor;
— be referenced to a moving platform such as a car, a ship, an aircraft or a spacecraft. Such a coordinate reference system can be related to a second coordinate reference system which is referenced to the Earth through a transformation that includes a time element;

— spatial coordinate reference systems in which coordinate values of points on or near the surface of the earth change with time due to tectonic plate motion or other crustal deformation. Such dynamic systems include time evolution, however they remain spatial in nature;

— parametric coordinate reference systems which use a non-spatial parameter that varies monotonically with height or depth;

— temporal coordinate reference systems which use dateTime, temporal count or temporal measure quantities that vary monotonically with time;

— mixed spatial, parametric or temporal coordinate reference systems.
