The 1:200'000 geotechnical map (GK200) shows the subsurface strata classified according to lithological-petrographic criteria. The legend is designed to represent the technical use of the subsurface (extraction of mineral resources, building projects). The map is overlaid with point data showing locations where unconsolidated and consolidated rock are mined and processed. The following sheets are available: Sheet 1, Neuenburg-Bern-Basel (1964); sheet 2, Lucerne-Zurich-St.Gallen-Chur (1963); sheet 3, Geneva-Lausanne-Sitten (1965); sheet 4, Bellinzona-St.Moritz (1967).
