Abstract

The Geological Survey of Japan (GSJ) carried out 3D geological mapping of central Tokyo. In this project, we performed surface-based geological modeling using borehole logs created by GSJ and also those provided by local governments as well as the development of the Web system for sharing 3D geoinformation. The 3D geological map of central Tokyo will be released on the “Urban Geological Map” website in a year. In this paper, we describe the current progress of this project.
