Application of GeogrAaphic Information System Technique in the Design of Gas Pipe Network Plan
Geographic Information System is widely used in different fields and it has different backgrounds and models these are introduced briefly in this article. Based on the analysis of development background, application and the related trends of development both at home and abroad for pipe network system, some problems are indicated, such as, building the pipe network geographic information system needs to grasp the key technology, including component technology, object-oriented design, databases and pipe network modeling technology, according to the data characteristics of gas pipe network and using MS Windows 2000 (Advance) Server or UNIX as operating system. The overall design plan of Daqing gas company pipe network information system based on the way of Web is put forward and selecting Windows 2000 Professional as client computing operating system for running the ArcInfo 9.x application program and using other geographic information system software to build the geographic information development platform that gives priority to the ArcGIS of ESRI company. The management method of geographic information system is mainly database, elaborating the implementation of all systematic functions and the management process of data and corresponding software and the development of user interface, the access to the database are finished as well. Design of user-interface is practical and convenient, which has the characteristics of easy and flexible operation situation and high visibility. Therefore, it indicates the application of geographic information system technique is to lay a solid foundation for the standardization of enterprises, in the meantime, it can effectively promote the urban construction and economic development.
