Digital Dufour Map
The Topographical Map 1:100,000 (Dufour Map) is the first modern official map series of Switzerland.

Topographical Map (Dufour Map 1:100,000)
It was first published between 1845 and 1865, and subsequently updated to 1939. Every edition has now been scanned and is available in digital form for research into the development of the Swiss landscape and a host of other applications.
The so-called Federal and Cantonal topographic surveys served as a basis for the publication of the Dufour Map. This is the first modern official map series of Switzerland.
All earlier editions are in the map collection.
