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 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 + ).
The geography of Switzerland features a mountainous and landlocked country located in Western and Central Europe. Switzerland's natural landscape is marked by its numerous lakes and mountains. It is surrounded by five countries: Austria and Liechtenstein to the east, France to the west, Italy to the south and Germany to the north. Switzerland ...
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 .
Many of the coordinates listed below are only approximate. As of 2020, there are 175 international tripoints. Africa has 61 international tripoints (the highest number of international tripoints), followed by Asia with 51, Europe with 48, South America with 13, and North America with two.
