Digital Old National Maps 1:25 000 / 1:50 000 / 1:100 000


Already from about 1900, the first tests for new map series of Switzerland were carried out. The 1935 Federal Act named the new and still used National Maps as the official map series of Switzerland. They supersede the earlier Dufour and Siegfried Maps.

All editions are preserved in our Map Collection. The National Maps do completely cover the country in the largest as well as the smallest scales.

Official name: Swiss National Maps

Ellipsoid: Bessel 1841

Projection: Conformal oblique cylinder projection
