232 Annexes
EXAMPLE
Between geodetic and Cartesian coordinate systems or between
geodetic coordinates and projected coordinates, or change ofunits such as from radians to degrees or feet to metres.
NOTE
A co ordinate conversion uses parameters which have constant values.
coordinate dimension
number of measurements or axes needed to describe a position in a co ordinate system (lS039 2003)
coordinate operation
change of coordinates, based on a one-to-one relationship, from one Coordinate Reference System to another (lS043 2003)
NOTE
Supertype of coordinate transformation and co ordinate conversion
Coordinate Reference System
coordinate system that is re1ated to the real world by a datum (lS043 2003)
NOTE
For geodetic and vertical datums, it will be related to the Earth.
coordinate system
set of mathematical roles for specifying how coordinates are to be assigned to points
(lS043 2003)
coordinate transformation
change of coordinates from one Coordinate Reference System to another Coordinate
Reference System based on a different datum through a one-to-one relationship
(lS0432003)
NOTE
A coordinate transformation uses parameters which may are derived empirically by a set of points with known coordinates in both Coordinate Reference Systems.
Coordinated Universal Time (UTC)
time scale maintained by the Bureau International des Poids et Mesures (International Bureau ofWeights and Measures) and the International Earth Rotation Service
(lERS) that forms the basis of a coordinated dissemination of standard frequencies
and time signals (lS040 2002)
curve
I-dimensional geometrie primitive, representing the continuous image of a line
(lS0392003)
NOTE
The boundary of a curve is the set of points at either end of the
curve. If the curve is a cyc1e, the two ends are identical, and the curve (if topologically c1osed) is considered to not have a boundary. The first point is called the start
point, and the last is the end point. Connectivity of the curve is guaranteed by the
"continuous image of a line" clause. A topological theorem states that a continuous image of a
connected set is connected.
