Underground planning

The deep subsurface is being exploited more and more. The underground planning project group of the Swiss Association of Geologists (CHGEOL) is campaigning in this field for sustainable concepts which are based on geological knowledge (© CHGEOL, Illustration Ines Senger).

Geological software

Geologists are dependent on support from numerous software applications for their daily work. Besides the classic Office applications, a multitude of specialized applications enable the useful analysis and representation of geological data sets.

Geological cartography

Geological maps display a multitude of geologically relevant information in a concise manner. They are an important basis for geotechnical and environmental decisions (© swisstopo).


The rock mass must be described and investigated in detail for the professional project planning and execution of underground structures. Here geologists and engineers must work closely together (© AlpTransit Gotthard AG).
