Swiss coordinate system

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. With the advent of GPS technology, a new coordinate system was introduced in 1995 under the name LV95 (Landesvermessung 1995, German for “land survey 1995”) after a 7-year measurement campaign.

LV is translated as MN in English.^[1]
