Constructor Detail

CoordinateReferenceSystem

public CoordinateReferenceSystem(CrsId crsId,
                                 String name,
                                 CoordinateSystem<P> coordinateSystem)

Constructs a CoordinateReferenceSystem.

Parameters:

crsId - the CrsId that identifies this CoordinateReferenceSystem uniquely

name - the commonly used name for this CoordinateReferenceSystem

coordinateSystem - the coordinate system to use

Throws:

IllegalArgumentException - if less than two CoordinateSystemAxes are passed.
