Research on Key Technologies of Integrated Management System of Underground Pipeline Network Based on WebGIS

This paper designs and develops an integrated management system of underground pipeline network based on WebGIS,focusing on the organization,storage,analysis and update of two-dimensional pipeline network data.ArcGIS is used as the basic GIS platform of the system;Python language is used to preprocess two-dimensional data;Model Builder is used to complete network analysis functions such as tube burst analysis and flow direction analysis;WFS service of OGC is used to support data updating;JavaScript and Asp.net language are used to build WebGIS system platform,which is finally realized.Various query,statistics,analysis,emergency and other functional modules,and in the Web browser for two-dimensional and three-dimensional linkage algorithm research,solve the two-dimensional system can not accurately and intuitively describe the three-dimensional information of pipelines,to achieve a real two-dimensional and three-dimensional integration system.Thus,it can provide assistant support for scientific and efficient management and effective decision-making of each ownership and business department.
