Design Of The Urban Drainning Pipe Network GIS

With the rapid development of urban construction, the protection of water environment is more and more important, the rain water and waste water treatment establishment has been gradually completed. And it brings a lot of data of draining pipe network and appurtenant works. It is very difficult to manage urban underground network (including the draining pipe network) by handwork method. It is necessary for modernization city to establish a perfect, exact draining pipe network GIS (Geographical Information System) to enhance management efficiency and quality of draining pipe network.Urban draining pipe network GIS is a new technology to store and manipulate spatial data, integrated with attribute data of draining pipe network for conveying information to the public and government officials in an easy-to-use GUI (Graphical User Interface) to meet municipal planner's requirement to manage, design and query the draining pipe network.Visual Basic and GeoMap which is a component GIS software developed by Wuhan GEO Information Science Ltd., are adopted to develop the draining pipe network GIS, to carry out management and analysis dada of the system by computer in virtue of spatial analysis of GIS. It is divided five modules: â…  .User management module, â…¡ .Waste water management module, â…¢.Rain water mangement module, â…£.Data management module, â…¤. Query statistics module, â…¥.Help module.The main function of user management module is to manage all the users. The function of waste water management module is to mange every information of the pipe net and export kinds of special maps(according to water target, flux and pipe diameter). The function of rain water mangement is to mange all informations of the rain pipe. The function of database management module is for database establishment, database maintenance, data input, data export. The function of query and statistics module is to manager the database of drainage pipe network, which was established by database management module. It includes four parts: data input, data search, data query, data statistics. The function of help module is to offer help for the system users.The thesis is based on the draining pipe network of Wuhan Zhuankou Economical Development Zone, discussing how to design urban draining pipe network GIS.
