Study and Application of the Urban Environmental Protection Information System Based on ComGIS
基于组件式GIS的城市环保信息系统的研制与应用

Through analysis of present situation of Informational Construction in Urban Environmental Protection Bureaus of China, the Urban Environmental Protection Information System based on ComGIS is designed in this paper. Key technologies such as data organization and functionality designation are studied, and development environment and integration technology are analyzed. Through analyzing the characteristics of environmental management of Yangzhou city, and establishing urban environmental geo-spatial data base and attribute data base, Yangzhou Environmental Protection Information System was developed based on comGIS, including Fundamental Map module, Accessing Data module, Geometry Object module, Output module, etc, as well as Fundamental Platform for Information sharing and Pollution Managing Subsystem. It realized visualization in managing information about environmental protection, and provided scientific supports for Yangzhou environmental management.
