| BursaWolfParameters | | public class BursaWolfParameters extends Formattable implements Cloneable,Serializable(Code) | | Parameters for a geographic transformation between two datum.
The Bursa Wolf parameters should be applied to geocentric coordinates,
where the X axis points towards the Greenwich Prime Meridian,
the Y axis points East, and the Z axis points North.
The "Bursa-Wolf" formula is expressed in matrix form with 7 parameters:
