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 (Swisstopo). A first coordinate system was introduced in 1903 under the name LV03 (Landesvermessung 1903, German for “land survey 1903”), based on the Mercator projection and the Bessel ellipsoid.
