Geological maps and data online
Has the Piz Bernina map sheet already been published? What kind of rock is my house built on? ... You can find the answer to these and other questions under the topic “Geology” in swisstopo’s viewer, “map.geo.admin.ch”.
Under “Topic Geology” (map.geologyportal.ch), you can find maps and data belonging to the Swiss Geological Survey and other institutions in the field of earth sciences. You can display the availability of the most relevant map series, as well as the respective maps and datasets themselves.
Whether geology is your profession or hobby, the viewer quickly provides information for preliminary investigations in geological projects or simply as a geological encyclopaedia.
map.geo.admin.ch serves as a visualisation tool for geodata for the whole of Switzerland. The viewer was developed by swisstopo, who also operates it.
