Study In WebGIS-based Three-dimensional Pipeline Management System

With the rapid development and mature of mapping technology, GIS technology, Internet technology, three-dimensional space technology and database technology,the design and construction of pipeline management system both at home and abroad has made rapid development, but in the networking, three-dimensional, multi User management and applications of the urban underground pipeline some problems still exist, which limits the widely use of urban underground pipeline management system.In order to promote the wide application of pipeline management system in urban planning and construction,this paper points at the lack exist in the construction of underground pipelines management system. Using WebGIS technology and spatial database technology, we designed the WebGIS-based three-dimensional main framework of the pipeline management system, proposed implementation method of three-dimensional in terrain and pipeline based on OpenGL,and proposed the method how to accomplish calling three-dimensional modules using ActiveX controls in the page,and implemented using Oracle 10G+ArcSDE as the terrain and pipeline storage database,simultaneously we use ArcGIS Server, Engine series of components for the development platform to build a WebGIS three-dimensional information management platform management, and urban planning work in practice to be applied.The system realizes the function such as Web publishing of pipe network data, graphic display, query statistics, location analysis and three-dimensional display, both to meet the urban underground pipeline data management needs, but also be able to complete the urban planning and design assistance, and can work for internet inquiry service, laid the foundation for the Digital Land and Digital City construction.
