GIS-based Approaches for Planning Support

摘要

Along with the development of Digital City and its practical applications, various urban geographic information systems (UGIS) has contributed enormously to the government's information services and decision-making process. However, the data redundancy has become a practical issue, which makes planners difficult to derive required data effectively from a large amount of data from UGIS databases. Based on comparison of the planning support system (PSS) with other UGIS, requirements of planning support based on GIS is discussed. Aiming at providing effective data and methods for urban planning, the paper explored GIS-based approaches for planning support in which spatial analysis played an important role and put forward a technological model to analyze urban problems in a dynamic environment to provide ideas and hints for further development of urban planning theories and practice.
