Siegfried Map

The original surveys for the Dufour Map were used for the publication of the 1:25,000 / 1:50,000 Topographic Atlas of Switzerland (Siegfried Map), which was produced between 1870 and 1926 as a co-operation between the federal government and the cantons, based on two Federal Acts dating from 1868. 

Section of the Siegfried Map in the area of Zurich. The map is multi-coloured. The city centre and lake can be seen. The detail from sheet 161 of the first edition of the Siegfried Map at 1:25 000 scale dates from 1881.
