The Siegfried Map projection was a cone equivalent, as for the Dufour Map. The print mode used for the 1:25,000 pages was initially intaglio, and from 1905 a printing plate. The 1:50,000 pages were printed via a lithography process, and from 1910 by intaglio. Until 1949, there were occasional revised editions of Siegfried Map pages.

The original images for the Dufour Map were created in 1:25,000 scale (for the Swiss plateau) and 1:50,000 (for the mountains). However, the Dufour Map was published in 1:100,000 scale, enabling the territory of Switzerland to be divided into 25 sheets, each of which measured 70 centimetres (28 in) x 48 centimetres (19 in).
In each scale, the whole of Switzerland was covered. In 1979, with the issuance of the last 1:25,000 scale sheet, the work was completed. The map sheets have been produced in several different versions: topographic maps, tourist maps, special maps (for aerospace, geology, etc.). They are now also available on electronic media.

Fertile arable land is constantly shrinking in Switzerland. The area statistics for 2005 show that between 1985 and 1997, agricultural and alpine areas decreased by 482 km 2 (186 sq mi). Most (64%) of this area has been allocated to housing (urbanization), the rest has turned into forest, mainly on steep highlands. [13]
