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.

Local European reference frames
In addition to European reference frame ETRF89 (GNSS network EUREF), national reference frames (triangulation / levelling) are still in use in all European countries. The local reference frames are adapted to the special requirements of a given region (e.g. Switzerland) and should therefore only be used in that region. National survey organisations provide information about these systems and their transformation parameters.
