An ILcdTopocentricReference
is an ILcdGeoReference
that is defined by a
geodetic datum and a lonlatheight point
that defines the origin of the topocentric coordinate system of this reference.
A topocentric coordinate system is a righthanded cartesian coordinate system with the following properties:
 Its origin is defined by a lonlatheight point on the ellipsoid.
 The yaxis is directed northwards and aligned to intersect with the polar rotational axis of the ellipsoid.
 The xaxis if directed eastwards.
 The xy plane is tangential to the ellipsoid at the origin.
 The zaxis is perpendicular to the ellipsoid at the origin, and points outwards. In other words, the zaxis is perpendicular to the xy plane.
This reference is also referred as an ENU (EastNorthUp) projection.
