Apply And Research Of Urban Water Supply Networks Information System Based On MAPGIS

Urban water supply networks information system is take the space information and property information of water supply pipelines as heart that it's closely related urban residents life, it's the information system that make use of computer technology, computer graphics technology, data manage technology, information visualization technology, and so on to equitable manage, plan, design, remake and conduct accident about the water pipeline. It's one of the signs of urban development and improvement, it's an inevitable outcome of the modern urban's information develop and play an important role in the urban planning and developing.In this paper, the author introduced the development, apply, some realize technology about urban water supply networks information system, and analysis the requirement and function about water supply networks information system, thus the author make a thorough investigation and research the topic about the apply and research of urban water supply networks information system based on MAPGIS.Firstly, the author made a penetration analysis of the research background and significance, the research situation at home and abroad and the expand orientation in future about the water supply networks information systems.Secondly, base on ample study about the requirement of water supply networks information system, analysis the structure and function about one city's in Zhejiang province, and utilize MAPGIS as system platform, VB secondary development on MAPGIS. In the face of system data structure, data management, it made a detailed analysis situation of water supply profession, ultimate realizes effective manages the water supply profession data.Lastly, the author introduce the main function, the realize process of networks 3D visualization, use OpenGL and VB can draw invented three-dimension scene, let the networks system provide more audio-visual and accurate management service for the urban water supply.
