The integration of urban spatial information : approaches from GIS and SOM

该研究促进了城市空间信息的整合，以更好地管理和政策分析的城市。(1)调查者以日本政府的“关键统计”为对象，总结了其属性，并从城市信息系统建设的角度考察了其使用的可能性。(2)使用集成数据库，研究者比较了传统的聚类分析方法和自组织映射技术，证明SOM方法可以更好地处理空间分析。(3)调查员介绍了日本在城市规划和电子政务背景下在各个历史阶段为城市一级信息系统和地理空间数据库所作的机构努力。分析了当前的形势，指出了存在的问题。

This research promoted integration of urban spatial information for better management and policy analysis in cities.(1) The investigator focused on the "key statistics" conducted by the Japanese government, summarized their properties, and examined the possibility of usage from the view of constructing urban information systems.(2) Using the integrated databases, the investigator compared the conventional cluster analysis methods with Self Organizing Map techniques and demonstrated that the SOM method can deal with spatial analysis better.(3) The investigator introduced Japan's institutional efforts on city-level information systems and geospatial databases in various historical phases in the context of urban planning and e-government. The current situation was examined and the problems were pointed out as well.
