This volume presents cases studies of applications of Geotechnology such as Geography Information Systems, virtual reality and cellular automaton and multi-agent systems in the field of urban planning and design. These are joint research presentations with students and colleagues from Asian universities in Japan and China. All these case studies refer to their application in Japanese or Chinese cities, which are on-field examples reflecting the enormous spread of geo-computation technology. Nevertheless, the concepts have wide applicability to other contexts. The studies can be classified into three types of Geotechnological applications at different levels in urban spaces, which are relevant to different kinds of urban planning and development projects. The book is comprised of three parts: Part 1: Geosimulation and land use plan Part 2: Geo Visualization and urban design Part 3: Geography information system and planning support.
