Design And Realization Of South-to-North Water Transfer Project Geographic Information System In HeNan Province Based On SuperMap Objects

As the ever-largest project in the world, South-to-North Water Transfer Project contains lots of works and covers many professional fields. Therefore, in order to realize a more scientific effective management and the scheduling function, the most advanced technology need to be introduced into the project.As the characteristics of South-to-North Water Transfer Project information is complex, so it is important to take advantage of the spatial data management and analysis function of GIS to develop a management information system with perfect function, well practicability and reliable running, which will improve the management efficiency and decision-making level. The essay takes South-to-North Water Transfer Project management in HeNan province as an example, the concrete content is as follows:(1) Discuss the practicability and necessity of South-to-North Water Transfer Project in the province of HeNan with GIS on consulting the domestic and foreign documents about the application of the GIS in hydraulic engineering and management.(2) The development of the geographic information system for South-to-North Water Transfer Project in the province of HeNan is the major content of the paper, the overall design, the goal, the principle, the structure, database design, the major functional design, input-output interface design and the realization of this system are discussed detailed in this paper. After that, the principles and the specific methods related are summarized. In the end, the final product of this system is displayed.(3) Component GIS technology is a newly developed advanced technology in recent years, so this system chooses SuperMap Objects to be GIS secondary component, current program language-Visual Basic as develop tool. The system has the function of querying, data store, management, statistics, figure display, analysis, simulation, output, decision making, forecast, etc.The system developed by this method is strong practical and feasible. The system mentioned above has the advantages of high quality, no-seam, efficiency, user interface friendly and fully functional, not only to make up the traditional visualization of the MIS deficiencies, but also give fully display to the GIS technology advantage.
