=== Siegfriedkarten ===
In 1865, [[Herman Siegfried]] becomes the Chief of the Topographical Bureau, and the bureau moves from [[Geneva]] to [[Bern]]. Over the next few years, a composite map is published of [[Ticino]], soundings start to measure the depth of the major Swiss lakes, and a first map is published scaled 1:250.000. In 1868, a Federal Act is passed to enforce the continuation of the initial topographic surveys, as well as the publication of the results. This results in new topographical surveys in 1869 and the publication of the first 13 ''Siegfriedkarten'' (1:25.000 and 1:50.000) in 1870. 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. In 1880, Herman Siegfried is succeeded by [[Jules Dumur]].

In 1895, the Topographical surveys for the ''Siegfriedkarten'' are finished. As of 1901, 581 sheets of the ''Siegfriedkarten'' have been published, with only a few individual more maps to come (there would be 604 maps in 1926). On old maps of the modern series, a reference to those maps can still be found: until the 1970s, the ''Siegfriedkarte'' was the best scale available for some areas of Switzerland, and therefore used by climbers and other [[Alpinism|alpinists]]. The printing of the ''Siegfriedkarten'' would continue until 1952.
