Development of the 3D geological model of the new railway line Dresden – Prague

The new Dresden - Prague railway line is a Saxon vision. Since 2014, the Geological Survey of Saxony has been developing the geological 3D model on the basis of archive data and geophysical investigations.

In cooperation with the TU Bergakademie Freiberg (TU BAF) and the Czech geological survey, a cross-border model was built that illustrates the complex geological structures in the underground of the route corridor. As part of an INTERREG project, the model was presented to the public in a walk-through 3D room at the TU BAF.

When the planning task was assigned to Deutsche Bahn, the geological 3D model proved its worth as a basis for the first steps of exploration planning, regional planning and preliminary planning in combination with GIS.

The model will be updated as knowledge is gained during the explorations.

It is a real pilot project for successful cooperation between authorities, research institutions and the railway companies in using graphic datamangement and 3D-modeling.
