Abstract: For the purpose of avoiding the emergence of isolated information islands and making full use of municipal information resources, this paper presents a scheme for a GIS-based dynamic integration of municipal management information. This scheme utilizes a hierarchical architecture. By selecting, filtering and synthesizing municipal information on facilities and operations, a composite municipal data warehouse is created and maintained. An integrated dynamic management mechanism for distributed municipal information ensures that the synthetic municipal data are complete and consistent with current status. Analysis and prediction can then be conducted based upon data mining techniques. Implementation of this scheme will improve the emergency handling capabilities of a city, urban planning, decision making and many aspects concerning service to society.
