Technical images
The technical images, as they are known, taken from the 1880s onwards are the oldest sub-collection in swisstopo’s image collection. It includes about 40,000 photographic objects. The photos predominantly show points in the national triangulation network. This sub-collection also documents how people used to work. It thus tells the story of the adventurous life of national topographers.
