Geodetic Reference frames
With the aid of the geodetic reference frames, the geodetic reference systems in the terrain can be realised and made usable, for example for practical measurement purposes, as the basis for geographic information systems. These reference frames are geodetic control (fixed point) networks and the permanent stations, the coordinates of which are specified in the reference system.
