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 ...

In 1958, the coordinate system of the maps is changed. Before 1958, the centre of the coordinate system, Bern, had coordinates (0, 0). From this moment, it has coordinates (600, 200). This is done so that any coordinate is either a x-coordinate or a y-coordinate: this prevents confusion about the order of the coordinates.
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 + ).
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
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 ...
BeiDou Coordinate System, China Terrestrial Reference Frame (CTRF) 2000 = ITRF97 at epoch 2000.0; own implementation. GLONASS PZ-90.11 is nominally its own system, but is quite close to ITRF and uses many of the same techniques. [2] National systems: United States: WGS 84 (see above); domestic use is mainly based on NAD 83 instead.
The geographical centre of Switzerland has the coordinates Swiss Grid: 660158/183641 It is located at Älggi-Alp in the municipality of Sachseln , Obwalden . The point is the centre of mass determined in 1988 by Swisstopo .
