A Unified E-Government Information Management Platform Based on Web GIS Technology

GIS plays an irreplaceable role in the e-government information management systems and has been widely applied in the economic, national defense and social sustainable government departments. This paper presents a unified framework of the e-government GIS information platform based on the J2EE and Web service technology to create an interoperable, distributed Web mapping system. The e-government GIS Web service defines a set of functions that clients may use to interact with the GIS servers. The client can interact with the servers through the related GIS web service. The platform can be integrated into other e-government systems for the spatial related information visualization through the Web GIS service. The e-government information that contained the geo-referenced data can be visualized with GIS distribution maps. The experiments show that the proposed GIS platform could plays an important role in e-government for spatial information management, broadcasting, data management, statistical analysis, and decision supporting.
