public class TLcdTopocentricCoordSysTransformation
extends Object
implements ILcdTopocentricCoordSysTransformation

A topocentric earth fixed cartesian coordinate system is a right-handed cartesian coordinate system defined with respect to an ellipsoid and a point on the ellipsoid. The coordinate system's origin is defined by a LonLatHeighPoint. The y-axis is aligned to intersect with the polar rotational axis of the rotational ellipsoid, and directed north-wards. The x-y plane is parallel to the plane tangential to the ellipsoid at the intersection point of the ellipsoid and the z-axis and goes through the given origin point. The z-axis is perpendicular to the ellipsoid and points from the center of the ellipsoid out-wards. In other words, the z-axis is perpendicular to the plane tangential to the ellipsoid at the intersection point of the ellipsoid and the z-axis. The x-axis is directed east-wards.
