Research And Application Of WebGIS Based On J2EE

The information of rural areas is the most important target in our country development.The application of WebGIS technology to information construction of rural areas can better solve the issue of the information release. That can provide visual access to information for the majority of the residents of rural areas to facilitate their living. At the same time, that can also enable outside to get a better understanding of rural areas, which helps to promote matchmaking and rural economic development.This paper firstly makes a brief introduction on the research background and significance, domestic and foreign literature review and research papers and paper organizations. It analyses the main problems about the information construction of rural areas. Then some design principles of information systems, as well as a systematic analysis of the needs and functional design, are addressed. The technology related to the use of WebGIS on the information construction is analyzed, after which the paper puts forward the technological means that should be used. The spatial database model of the rural area information system is analyzed, which focuses on data storage means. After that, it puts forward the database model applicable to the construction of rural area information. The open source software—PostGIS is researched. This paper designs the information system architecture of rural area. The four-storey information system Model is built, and The open source software—GeoServer is researched. At last, the information system of rural area based on WebGIS is designed and implemented.
