Swiss coordinate system Swiss coordinate system The Swiss coordinate system (or Swiss grid) is a geographic coordinate system used in Switzerland for maps and surveying by the Swiss Federal Office of Topography (Swisstopo). The map projection used is Oblique Mercator on an 1841 Bessel ellipsoid. The geodetic datum CH1903 (SRID 21781) uses as fundamental point the old observatory of Bern ( (WGS84)), the current location of the "Institut für exakte Wissenschaften" of the University of Bern. In order to avoid errors during coordinate transmissions, the coordinates of this point are 600'000 m E / 200'000 m N. The 0 / 0 coordinate is
