Research On GIS Of Pipeline Of Daqing Nature-gas Company

This paper is "Daqing gas company network management information system of the investigation report" in Daqing.Gas company limited company of the geographic information system establishment, development, and functional requirements, platform, the development cycle and development costs are investigation and analyzed, etc. Synthesizing network structure of the geographic information system and the data flow, this paper expounds the functions of this system and data management process, for three geographic information system software developers under investigation and GIS application platforms compared.GIS technology is an object of a comprehensive edge discipline and application technology that contains geography, measurement, and the computer and application object knowledge, etc.GIS in the developed countries has now entered industrialization and commercialization stages. GIS uses database to manage system., to be data and attribute data storage, processing and unity are analyzed. Establish for gas network maintenance, planning, design, construction and the pipe line, repair the completion of decision-making and attribute data query information space. Users can easily inquiry statistics, operating scheduling and file management. At present, GIS technology application level improved, the software platform of highly integrated and customized level unceasingly deepened, owning the independent copyright of homebred platform software function and application level improved, development department and the use of GIS technology department knowledge level to the GIS improved, the time that starting city network geographic information system is ripe.
