THE STUDY AND MANAGEMENT OF THE URBAN PIPELINE NET MAPPING AND ANALYING ON MAPINFO

The urban underground pipeline is the one of the most important parts of infrastructure. It is the key for urban planning, managing and constructing. However, with the urban enlarge, the pipeline net become more and more large and complicated. So it needs scientific management. GIS is the new technology, and it can be applied to the pipeline management. With the help of GIS’s functions of spatial analyzing, the pipeline net can be designed, managed and constructed easily. This paper mainly discuss the methods of pipeline mapping, which include the methods of data collection, the data file structure design and the approach to integrated indoor mapping with the field data collection. And how to dig out the knowledge by the longitudinal and lateral section analyzing on MapInfo, which include some algorithms research and section data file structure design and the methods of section maps mapping and outputting to user. In this paper, the method of pipeline mapping is studied in detail with using the data of field collecting. And the some data file structures are designed. Meanwhile, the methods of pipeline section mapping and analyzing are studied. Then the simulation run is done by using the field collecting data in Zhenjiang city Jiangsu provence China. The results of simulation are satisfied very much
