Both topics are addressed by the tool MO2GEO, which is flexible enough to allow the insertion of common national geological standards (UK, Germany, US). Borehole graphics and cross-section development are available, and the database extended by these data allows for an improved interpolation compared to borehole data only. The visualization of the pseudo-3D volumes shows not only the connected surfaces of geological layers but also virtual cross sections and boreholes at any defined points or lines inside the area. The tool MO2GEO is OpenSource and can therefore be used in schools as well.
