• Creates a new topocentric reference based on the given options.

    A topocentric coordinate system is a right-handed cartesian coordinate system with the following properties:

    • Its origin is defined by a georeferenced point.
    • The y-axis is directed northwards and aligned to intersect with the polar rotational axis of the ellipsoid.
    • The x-axis is directed eastwards.
    • The x-y plane is tangential to the ellipsoid at the origin, or at least symmetric with that tangential plane, in case the origin does not lie on the ellipsoid. This basically means that the axes are straight lines that do not follow the curvature of the globe.
    • The z-axis is perpendicular to the ellipsoid at the origin, and points outwards. In other words, the z-axis is perpendicular to the x-y plane and denotes height.
    • The unit of measure on all axes is 'meter'.

    The topocentric reference uses the same geodetic datum as the origin point's coordinate reference.
