From graphic plans to digital data
Since the introduction of the official cadastral survey in 1912 (when the legal framework of the Swiss Civil Code came into force), quality has been continuously improved and technical developments have been incorporated; this has led to the establishment of a variety of levels of quality. Although originally the data was captured purely by graphical methods and then transferred onto the land registry plans, the cadastre has now embraced modern information technology so that today the data is captured and fully structured in pure digital form.
