Zusammenfassung:
The Swiss Geological Survey (SGS) produces a suite of 3D geological models – both structural and parametric - in an established production environment, on a nation-wide basis. Output consists of regional-scale models of the deep subsurface (e.g. geological and temperature model of the Swiss Molasse Basin) as well as local-scale models of the shallow subsurface, with varying degrees of content and complexity. In addition, a new profile-based approach is currently being implemented – primarily using surface and shallow subsurface data - in order to expand the regional-scale model suite to cover the Jura region of Switzerland.

Modelling activities follow different approaches and workflows, depending on the types of available data and the planned uses of the various models. These data need to be in a geometrically, tectonically and stratigraphically harmonized state prior to modelling. This key requirement is made possible by the processes and standards that have been developed and implemented here at SGS e.g. legends, vector maps.

All of these models are stored and managed in the 3D database “GST” which is then used a source for directly publishing the 3D models to web- and app-based 3D-viewers or indirectly for other VR content. In the future, the SGS plans to enlarge the suite of models and streamline the production process.

Our presentation focuses on the latest developments as well as examples of the aforementioned regional- and local-scale models.
