A 3D block model of the Born–Engelberg structure in the border area of four map sheets derived from the GeoMol dataset. The heterogeneous 2-dimensional datasets, draping the digital elevation model, were harmonised according to the HARMOS results, simplified and reduced to bedrock maps. An example of such a bedrock map is depicted in the Hauenstein map sheet area. Light colours represent bedrock surfaces beneath Quaternary deposits, which were delimited by subcrop lines (blue dashed lines). The simplified harmonised bedrock maps were combined with existing geological profiles in order to establish the 3D model
