The Swiss coordinate system (or Swiss grid) is a geographic coordinate system used in Switzerland and Liechtenstein for maps and surveying by the Swiss Federal Office of Topography . A first coordinate system was introduced in 1903 under the name LV03 ( Landesvermessung 1903 , German for “land survey 1903”), based on the Mercator projection ...
Given that every projection gives deformations, each country's needs are different in order to reduce these distortions. These national projections, or national Coordinate Reference Systems are officially announced by the relevant national agencies. The list below is a collection of available official national projected Coordinate Reference ...

The Bessel ellipsoid (or Bessel 1841) is an important reference ellipsoid of geodesy.It is currently used by several countries for their national geodetic surveys, but will be replaced in the next decades by modern ellipsoids of satellite geodesy.
The National Maps of Switzerland, also referred to as the Swisstopo maps, are a set of official map series designed, edited and distributed by Swisstopo, the Swiss Federal Office of Topography. Each map series is based on an oblique, conformal , cylindrical projection ( Mercator projection ), with a Swiss Coordinate system ( CH1903 + ).
During the 1990s, Switzerland embarked upon a major programme of modernization and improvements across its railway infrastructure. [3] The NRLA initiative sought to provide better alternatives to the steep mountain railways across Gotthard, Ceneri and Lötschberg through the construction of a number of base-level tunnels that enabled trains to more rapidly and efficiently traverse the Swiss Alps.
The Siegfried Map projection was a cone equivalent, as for the Dufour Map. The print mode used for the 1:25,000 pages was initially intaglio, and from 1905 a printing plate. The 1:50,000 pages were printed via a lithography process, and from 1910 by intaglio. Until 1949, there were occasional revised editions of Siegfried Map pages.
Brig railway station. Brig railway station is an important railway junction in the municipality of Brig-Glis (French: Brigue-Glis), in the Canton of Valais, Switzerland.Opened in 1878, it is adjacent to the northern portal of the Simplon Tunnel and is served by two standard gauge lines.
