Georeferenced Siegfried Map
The Topographical Atlas of Switzerland was published over the period from 1870 to 1926. This was the first complete detailed map series for the whole of Switzerland. It was published at 1:25'000 scale for the lowland areas of the Mittelland, the Jura and south Ticino, and at 1:50'000 scale for alpine regions. With periodic campaigns of revision up to 1949, in all over 4000 revised sheets were published. 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 Siegfried Map - a unique national treasure in digital form.
- Historical maps as a guide for studying the changing landscapes and for historical research.
- The Central Plateau, the Jura Mountains and southern Ticino at the scale 1:25'000, and the Alps at the scale 1:50'000.
- Over 4000 maps with various dates of issue.

The first official map series were originally published in 1870 at the same scale as the topographic surveys (1:25'000 and 1:50'000). However, Switzerland was divided in two parts: one published in 1:25'000 scale, the other in 1:50'000 scale, both partly overlapping:
