A set of quantities from which other quantities are calculated.
For the OGC abstract model, it can be defined as a set of real points on
the earth that have coordinates. EG. A datum can be thought of as a set of
parameters defining completely the origin and orientation of a coordinate
system with respect to the earth.
A textual description and/or a set of parameters describing the
relationship of a coordinate system to some predefined physical locations
(such as center of mass) and physical directions (such as axis of spin).
The definition of the datum may also include the temporal behavior (such
as the rate of change of the orientation of the coordinate axes).
