A GM_Geodesic consists of two distinct positions joined by a geodesic curve. The control points of a GM_Geodesic shall all lie on the geodesic between its start point and end point. Between these two points, a geodesic curve defined from the ellipsoid or geoid model used by the coordinate reference system may be used to interpolate other positions. Any other point in the controlPoint array must fall on this geodesic.<br/>
