EarthLocalCoordinate

public EarthLocalCoordinate(J3Vector origin,
                    double alpha)

Constructor. Rotation angle in x'-y' plane should be given to define those axises directions.

        J3Vector origin :  Origin location vector. Should be represented in
                           EarthCenterCoordinate system.
        double alpha    :  the final rotation angle [rad] to determine
                           the x and y axis directions. 0 correponds to
                           y axis pointing to local south, Math.PI to
                           y axis poing to local north.
        

EarthLocalCoordinate

public EarthLocalCoordinate(J3Vector origin)

Constructor.

        J3Vector origin :  Origin location vector. Should be represented in
                           EarthCenterCoordinate system.
        

Y axis points to local south

EarthLocalCoordinate

public EarthLocalCoordinate(J3UnitVector nz,
                    double alpha)

Constructor. This is a special constructor when the origin is (0, 0, 0).

        J3Vector nz   :  the unit vector to define the z-axis of this local coordinate.
        double alpha  :  the final rotation angle [rad] to determine

                         y axis pointing to local south, Math.PI to
                         y axis poing to local north.
        

EarthLocalCoordinate

public EarthLocalCoordinate(double height,
                    double longitude,
                    double latitude,
                    double alpha)

Constructor. Origin location described by longitude, latitude, hight from the earth center.

        double height :  height [cm] from the earth center
        double longitude : longitude [deg]
        double latitude :  latitude [deg]
        double alpha    :  the final rotation angle [rad] to determine
                           the x and y axis directions. 0 correponds to
                           y axis pointing to local south, Math.PI to
                           y axis pointing to local north.
