Research And Implementation Of Urban Underground Pipeline3D Visualization System

The urban underground pipeline is an important part of urban construction, the city isalso the lifeline for survival and development, involving all parts of the city, and is closelyrelated to people’s lives. Pipeline data with large-scale, wide range of pipeline wide range ofcomplex spatial distribution, changes, growth speed, long development time and so on.The traditional two-dimensional line chart difficult for a large number of pipelineinformation for effective description and expression, it does not directly reflect the spatialdistribution of underground pipelines, so we need to be able to visually describe thedevelopment of three-dimensional feature space between the pipeline and the pipeline3Dpipeline model of relations for the realization of three-dimensional display and managementof the pipeline, so that makes the plane had become clarity display intricate pipeline.The urban underground pipeline management system is based on three-dimensionalcomputer network as the carrier, GIS software application technology platform, theintegration of urban underground pipeline data integrated resource management to achieve athree-dimensional visualization of underground pipelines, storage, query, analysis, positioningand other functions, formed a perfect urban underground pipeline data resource managementintegrated digital, three-dimensional visualization pipeline system.This paper closely with the design and implementation of urban underground pipeline3Dvisualization system this problem, the system first spatial database technology (SDE),three-dimensional visualization technology and real-time dynamic information collection andupdating technology, analysis, and then the data involved in the system managementtechnology, data visualization and query analysis dynamic display technology solutions totechnical problems, such as in-depth discussions, which made an effective response options.As a basis for research fit with organizational management timeliness city pipeline data, andthe establishment of a city pipelines database designed automatic batch data warehousing strategy, to achieve a new pipeline automatic data storage, and creatively presented newpipeline data mapping program automatically saves manpower, and combined with each otherand existing digital city technology, allowing users to visually browse in a three-dimensionalvirtual city on the scene and analyze pipeline data.This paper aimed at the city underground pipeline data, This paper the characteristics ofurban underground pipeline data, research and implement a set of city pipeline data collection,management,3D visualization and spatial analysis functions in one city pipeline datamanagement and visual query system, working for science and urban planning by real-timedata analysis and use of pipelines laid the foundation for the city, providing convenient andeffective tools and decision support.
