      • FieldGeodeticPoint

        public FieldGeodeticPoint​(T latitude,
                          T longitude,
                          T altitude)
        Build a new instance. The angular coordinates will be normalized so that the latitude is between ±π/2 and the longitude is between ±π.
        Parameters:
        latitude - latitude of the point (rad)
        longitude - longitude of the point (rad)
        altitude - altitude of the point (m)

    • Method Detail

      • getLatitude

        public T getLatitude()
        Get the latitude.
        Returns:
        latitude, an angular value in the range [-π/2, π/2]

      • getLongitude

        public T getLongitude()
        Get the longitude.
        Returns:
        longitude, an angular value in the range [-π, π]

      • getAltitude

        public T getAltitude()
        Get the altitude.
        Returns:
        altitude

      • getZenith

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getZenith()
        Get the direction above the point, expressed in parent shape frame.

        The zenith direction is defined as the normal to local horizontal plane.

        Returns:
        unit vector in the zenith direction
        See Also:
        getNadir()

      • getNadir

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getNadir()
        Get the direction below the point, expressed in parent shape frame.

        The nadir direction is the opposite of zenith direction.

        Returns:
        unit vector in the nadir direction
        See Also:
        getZenith()

      • getNorth

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getNorth()
        Get the direction to the north of point, expressed in parent shape frame.

        The north direction is defined in the horizontal plane (normal to zenith direction) and following the local meridian.

        Returns:
        unit vector in the north direction
        See Also:
        getSouth()

      • getSouth

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getSouth()
        Get the direction to the south of point, expressed in parent shape frame.

        The south direction is the opposite of north direction.

        Returns:
        unit vector in the south direction
        See Also:
        getNorth()

      • getEast

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getEast()
        Get the direction to the east of point, expressed in parent shape frame.

        The east direction is defined in the horizontal plane in order to complete direct triangle (east, north, zenith).

        Returns:
        unit vector in the east direction
        See Also:
        getWest()

      • getWest

        public org.hipparchus.geometry.euclidean.threed.FieldVector3D<T> getWest()
        Get the direction to the west of point, expressed in parent shape frame.

        The west direction is the opposite of east direction.

        Returns:
        unit vector in the west direction
        See Also:
        getEast()
