ArcGIS-based Three-dimensional Virtual Simulation Of Underground Pipelines And Implementation

Urban Underground is the city an important part of the infrastructure by the criss-cross drainage, water supply, electricity, telecommunications, and industrial pipeline natural gas composition, with the city's development and construction, underground pipeline system is also too large, many cities have established Chengshiguanwang corresponding geographic information systems. But now the pipe network visualization of geographic information systems are mostly two-dimensional plane, do not display the spatial relationship of various pipeline, therefore, underground pipe network geographic information system visualization is imminent, Based on the summary and analysis of progress, based on the underground pipeline described the basic problem of visualization, this study also points out the idea of the existing software to fully study the theory and techniques proposed to achieve the city underground pipe network visualization system and design the optimal solution, innovative pipeline proposed two-dimensional data on the existing three-dimensional technology and a three-dimensional component model library, the establishment of an underground pipe network general three-dimensional virtual reality simulation data model, implemented urban underground pipe network visualization system.This full use of ESRI's GIS software platform to achieve the three-dimensional visualization of urban underground pipe network into the target, and PROCAD 3DSMART ARCGIS technology practice and a flexible tube library program designed to establish practical and efficient software solutions, is the software designed with high practicality and feasibility, the economic development to reduce duplication and waste of resources. Through this software product design and professional GIS design theory, technology research and software products implementation, designed for urban construction, planning departments, professional pipeline units meet the following basic requirements to provide a stable, mature, efficient, scalable and sustainable development and application of three-dimensional urban underground pipeline information management platform for virtual reality simulation...
