Abstract coordinate reference system, consisting of a single
Coordinate System and a single
Datum (as opposed to Compound CRS).
A coordinate reference system consists of an ordered sequence of coordinate system
axes that are related to the earth through a datum. A coordinate reference system
is defined by one datum and by one coordinate system. Most coordinate reference system
do not move relative to the earth, except for engineering coordinate reference systems
defined on moving platforms such as cars, ships, aircraft, and spacecraft.
Coordinate reference systems are commonly divided into sub-types. The common classification
criterion for sub-typing of coordinate reference systems is the way in which they deal with
earth curvature. This has a direct effect on the portion of the earth's surface that can be
covered by that type of CRS with an acceptable degree of error. The exception to the rule is
the subtype "Temporal" which has been added by analogy.
