Swisstopo

Swisstopo is the official name for the Swiss Federal Office of Topography,[a] Switzerland's national mapping agency.

[1] The main class of products produced by Swisstopo are topographical maps on seven different scales.

[2] The numbering system of Swiss regular maps (apart from composites) is directly based on the geographical situation.

However, as can be seen on the Seite nicht gefunden,[3] there are some exceptions to this rule: Switzerland is a little bit too large to be only 20 1:25.000 maps wide.

Instead of choosing another system, the map to the east of 1199 Scuol is called 1199bis Piz Lad.

This bureau published its first map the same year, the Carte topographique du Canton de Genève.

To honour Dufour, the Swiss government decided to rename the highest peak on the Dufourkarten from Höchste Spitze to Dufourspitze: it still carries that name today.

In 1863, the SAC published a 1:50.000 map of the region Tödi, based on unpublished survey material.

In 1868, a Federal Act is passed to enforce the continuation of the initial topographic surveys, as well as the publication of the results.

In 1878, a 1:1.000.000 map is published, and the next year, the height of the Pierre du Niton is measured to be 376.86 metre.

On 21 June 1935, a Federal Act was passed on the production of the new National Map series, ranging in scale from 1:25.000 to 1:1.000.000.

[clarification needed] For this purpose, a 'M18d' Messerschmitt was bought for aerial photography, the first aircraft owned by the Eidgenössischie Landestopographie.

The 1:100.000 series started with 41 Col du Pillon (1954), and finished with 47 Monte Rosa in 1965.

With the publication of the latter map, the work required by the Federal Act of 1935 was finally finished.

Since 1951, different sorts of leisure maps have been published by the Federal Office of Topography.

As can be seen here, the map 45 Haute Savoie only has a very little spot of Switzerland on it, in the extreme north-western corner.

Some maps have been published in the past, but have been discontinued, also because they lack any part of Switzerland.
