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 ...
Type Point Location Canton Elevation Coordinates highest point: Monte Rosa: Zermatt: Valais: 4634 m: lowest point: Lake Maggiore: Locarno (district) Ticino: 193 m
The following list is a comparison of elevation absolutes in Switzerland. Data includes interval measures of highest and lowest elevation for all 26 cantons, with coordinates of the highest. Location names, mean elevation, and the numeric differences between high and low elevations are also provided.
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 + ).
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.
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 fits especially well to the geoid curvature of Europe and Eurasia.Therefore, it is optimal for National survey networks in these regions, although its axes are about 700 m shorter than that of the mean Earth ellipsoid derived by satellites.
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 .
