Based On Supermap Objects Of The City Water Supply System Design And Realization

City water supply pipe Geography Information System is interactive information management software which aimed of solving the problems for the water supply companies and city planning management department.For designing software I used activeX controls, I took the city water supply pipe web as my research object, using the Real-time management technology to manage the water supply pipe web, GIS to do the analysis,This software has powerful function in simulation and forecast, it provide decision-making support for the city water supply pipe web layout, design, construction, and optimal flow under various circulate estate.This system has a friendly interface, simple manipulated and complete functions; it is a powerful instrument for the scientific management of city water supply pipe web.The past MIS (management information system) can not meet the requirement of the city water supply pipe web now.It lacks very much behind in efficiency therefore a new computer management system came out: GIS (geography information system) .The main character of it is: the veracity in management, the standard MAP to provide direct judgement and the definite corresponding between void relationship and real object, intuitionist in management.Meanwhile this system include the analysis system, it provide expert analysis for the city water supply pipe web design, transport and allot character, attempter, analyzing the emergency, safety evaluation. It provide great convenience for the water supply companies.As the swift development, if the city fundamental construct, city water supply pipe web sharply expanded, it becomes very complicated. The traditional manual way of collection, manage, modify water supply pipe web data can not meet the requirement of development.City water supply pipe web information system as the specialist application of GIS, provided a brand new technology for the management, layout, design in water supply companies and city management decision-making department. It also provides the absolutely necessary fundamental data for city water supply pipe web department.The set up of water supply pipe web database will create social as well as the commercial benefit for the...
