public interface CoordinateSystem
extends IdentifiedObject

The set of coordinate system axes that spans a given coordinate space. A coordinate system (CS) is derived from a set of (mathematical) rules for specifying how coordinates in a given space are to be assigned to points. The coordinate values in a coordinate tuple shall be recorded in the order in which the coordinate system axes associations are recorded, whenever those coordinates use a coordinate reference system that uses this coordinate system.

Method Detail

getDimension

int getDimension()
Returns the dimension of the coordinate system.

Returns:
The dimension of the coordinate system.

getAxis

@UML(identifier="usesAxis",
     obligation=MANDATORY,
     specification=ISO_19111)
CoordinateSystemAxis getAxis(int dimension)
                             throws IndexOutOfBoundsException
Returns the axis for this coordinate system at the specified dimension. Each coordinate system must have at least one axis.

Parameters:
dimension - The zero based index of axis.
Returns:
The axis at the specified dimension.
Throws:
IndexOutOfBoundsException - if dimension is out of bounds.
