基于GIS的市政管理信息集成方案及关键技术

Scheme and Key Techniques for GIS-Based Integration of Municipal Management Information

为了有效避免信息孤岛现象,充分发挥市政信息资源的作用,提出基于GIS的市政管理信息动态集成方案。采用多层体系结构,通过对市政设施和业务信息的筛选、过滤和综合,形成市政综合数据仓库,通过分布式一体化动态管理机制保证数据的现势性和完整性,利用数据挖掘技术进行分析和预测.该方案的实施,将有利于提高城市的应急处理、规划决策和社会服务能力.

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.
