“Urban Geological Map” is developed by 3D modeling of geological strata in urban areas, based on borehole logs and other geological and geomorphological data. The web-based application outputs 2D and 3D geological maps, cross-sections along the arbitrary lines, and borehole data used for 3D geomodeling. This new style of geological map is under development in the Tokyo metropolitan area.
