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.
Global reference frames
The connection of Switzerland with the global reference frames is possible through different systems.
Local Swiss reference frames
Local reference frames are adapted to the special requirements of a given region (e.g. Switzerland) and should therefore only be used in that particular region. The following local frames are used in the national survey.
Transformations (3D / position)
For handling spatial data, it is important to have an easy and accurate transition between the various reference systems and frames. swisstopo offers suitable transformation methods for all applications, either through online services over the Internet or commercially available geodetic software.
Height transformation
swisstopo offers suitable transformation methods for all applications, either through online services over the Internet or commercially available geodetic software.
