The Design And Implementation Of Deyang Underground Pipeline Information Management System

Urban underground pipeline information management system is an important partof a digital city. To determine the exact distribution of urban underground pipeline andestablish a comprehensive Urban Underground Pipeline Information ManagementSystem are the premise of urban daily management and construction.3D pipelinesystem is produced by processing2D pipeline.According to the2D pipeline message,3D underground pipeline can display and analyse data in three-dimensional space.In the process of building the Deyang City Underground Pipeline InformationManagement System, there are5technologies in use, such as C/S development model,spatial database, AE secondary development component and Skyline3D modeling andArcSDE spatial database engine technology. This study aims at implementation ofDeyang City Underground Pipeline Information Management System to achieveuniform management of various types of pipelines. The detailed information issummarized as follows:1．According to Deyang City underground pipeline’s characteristics, we havedesigned the underground data structure and pipeline database. By using this technology,spatial and attribute data can be stored in integration.2． Combined with UAV high-resolution images and digital elevation model(DEM), we have built the ground’s three-dimensional scenes and lines’ node model.More than that, by accessing pipeline network database, we can generate3D modelpipeline data real time using ArcSDE technology.3． Deyang City Underground Pipeline Query Management System has beendeveloped by using vs2008、AE、Skyline、ArcSDE technologies. It has many queryfunction modules.
