Editing Swisstopo (section)

=== New century ===
In 1887, the first maps with relief shading are published. In 1889, a photographic studio is appended to the bureau. In the years after 1894, a wall-map for schools is published, in response to a request from the parliament to do so. In 1898, the soundings of the major Swiss lakes are finished. In 1901, the bureau is moved into an independent division within the military, and the name ''Eidgenössische Landestopographie'' becomes customary, a name still used by some people until today, and a name which can be found on some older maps. [[Hermann Kümmerly]] publishes a relief wall-map for schools in the same year. In 1908, map trials are started to serve as a replacement for the ''Dufourkarten''. Two years later, trials start to replace the ''Siegfriedkarten''. Much of this military work would remain secret for many years. In 1913, 1922 and 1924, trials are done with [[aerial photogrammetry]], first with balloons and later with aircraft, but only as of 1930 this is used for production of maps, and in 1940 terrestrial photogrammetry is abandoned.
