This volume presents case studies of the application of Geotechnology such as Geoinformation system, virtual reality and cellular automaton and multi-agent system in the field of urban planning and design. These are joint research presentations with students and colleagues from Kanazawa University. All these case studies are about the application in either Japanese or Chinese cities, which are on the field examples reflecting widespread geocomputation technology. Nevertheless, the concepts have wide applicability to other contexts. The cases can be classified into three types of geotechnological applications on different levels of urban spaces, which are relevant to different kinds of urban planning and development projects. The main focus of this book is comprised of three parts: 1. Geosimulation and land use plan (at the level of urban and regional area,land use plan).- 2. GeoVisualization and urban design (at the level of urban partitions, urban design of street furniture, townscape and public parks.-3. Geography Information System and planning support (concerning development and planning support tools based on GIS platform.
