The Swiss Geological Survey

The Swiss Geological Survey at swisstopo is the federal competence centre for the collection, analysis, storage and provision of geological data. It produces basic geological data, 2D and 3D models and manages the Mont Terri rock laboratory in St. Ursanne.

The Swiss Geological Survey compiles basic geological knowledge and archives analogue and digital data

As the unit of the federal administration responsible for earth sciences, the Swiss Geological Survey focuses on the organisation of geological studies of the country (geology, geotechnics and geophysics). It develops basic principles for the utilisation and protection of geological resources in the Swiss subsurface and makes these available to the public. Specialists from the Swiss Geological Survey develop 3D models to visualise complex geological issues. The Swiss Geological Survey advises and supports authorities in technical matters, publishes reports and drafts geological expert opinions.

The Geological Survey collaborates closely together with a variety of specialised associations and organisations, including the Swiss Academy of Sciences (SCNAT), the Georesources Switzerland Group, the Swiss Geophysical Commission (SGPK), the Federal Geological Commission (FGC) and various private-sector bodies (CHGEOL, GEOTHERMIE.CH, etc.). At the federal level, the Swiss Geological Survey is represented in the Federal Coordination Body for Geology (KBGeol), and at cantonal level in the Conference on Geological Subsurface (KGU). It is internationally active as the Swiss representative of the European Geological Surveys (EuroGeoSurveys, EGS). The Swiss Geological Survey also runs the office of the Federal Geological Commission (EGK).

Tasks

The Swiss Geological Survey is responsible for the provision and updating of geological, geotechnical and geophysical data and information for sustainable development and makes these available to all interested parties. It compiles comprehensive geological data of national interest in the form of 2D and 3D models and reports on the occurrence and supply of raw materials in Switzerland. Research into the subsurface disposal of CO2 and radioactive waste is essential for society, the environment and science. The Swiss Geological Survey operates the Mont Terri research laboratory in St. Ursanne, where more than 20 partner organisations from Switzerland and abroad carry out research activities.

Organisation

The Swiss Geological Survey comprises the Administrative Unit and the following four processes:

  • Data management 
  • National geological mapping with the sub-processes Jura, Plateau and Alps
  • Georesources
  • Rock laboratory and deep geological disposal
