Design Of Water Supply Network Geographic Information System Based On Graphic Engine

Currently,with the rapid development of chinese economic construction,the lack of water resources is becoming more and more serious.In order to utilize water resourcesrationally and improve the efficiency of managing the pipe network information,various types of water supply network systems are applied to different water enterprises.However,In the process of development of the actual water supply network system,the development of different water supply network systems is often dependent on some kinds of existing graphics engine softwares,such as AutoCAD,MapInfo,ArcGISetc,different graphics engine software s Because of their different industries and the use of the different people,theiremphases of developmentare different,such as AutoCAD focus on the graphics display and processing,Map Info focus on geospatial information construction and storage,and ultimately leading to the development of water supply network system is restricted by the corresponding graphics engine software,and can't meet the actual requirements.This paper is based on the actual water supply enterprise,combined with the idea of component software technology and development of system,according to the actual project requirements,developing the water supply network system which meets the actual requirements.First of all,In the development environment of Visual Studio,by using the theory of graphics transformation and processing,designing to prepare a water supply network data visualization graphics engine interface by using C# programming language,achieving the graphics display,drawing and processing functions,getting rid of the restrictions of third-party software;Then,using Sql Server to establish database of water supply network,achieving the information storage of water supply pipe network buildings,pipelines and related components,and can access the database data,to carry out some professional calculation and analysis;Finally,accordingthe actual project needs,I complete the development of different functional modules.Currently,the system is in the testing stage,it realizes all the functions required in the enterprise business operations,including graphic display,editing and production,the management,query and statistics of pipe network information,generating reports,data conversion,Beforeputting into use officially,it is necessary to make further tests to verify.
