Topographic Atlas of Switzerland
The Topographical Atlas of Switzerland , unofficially also called Siegfriedatlas or Siegfriedkarte , is an official map of Switzerland , the publication of which was started by the Federal Topographical Bureau under Hermann Siegfried and lasted from 1870 to 1922. Since it is not an atlas according to today's usage , the map historians speak of the Siegfried map today .
The Siegfried map is based on the original recordings that had already been made for the Dufour map . The scale is 1: 25,000 in the plains and the Jura and 1: 50,000 in the Alps . The area on the first scale was divided into 462 sheets, the other area into 142 sheets, with the two areas overlapping in places.
Revised new editions of these sheets appeared by 1949. From 1952 Siegfried and Dufour maps were replaced by the new national map of Switzerland .
In contrast to the Dufour map , but consistent with the wild map , the Siegfried map shows the terrain with height curves. Three colors were used for the print: brown for the height curves in overgrown terrain, blue for bodies of water and for height curves on glaciers and black for the rest.
