摘要
三维GIS能够较准确和高效地实现燃气管网的设计和管理,由此探讨了ArcGIS实现三维燃气管网的仿真。从数字高程和数字地形三维建模生成周边环境,到应用三维管线设计技术生成管网矢量数据,介绍了三维管线仿真环境建模原理,以及使用ArcGIS实现三维燃气管网仿真的系统层次结构和功能扩展,并且应用实例,展示系统设计开发的可行性和实际应用效果。
The 3D GIS is used to design gas-pipelines accurately and manage it efficiently, based on which, the simulation of 3D gaspipelines are discussed by applying ArcGIS. It is from the scene of born through digital elevation model and digital terrain model to apply the design technology of 3D pipelines to shape the vector data of pipelines. Furthermore, the modeling theory of 3D simulation of gas- pipeline and the structure of the simulation system of 3D gas-pipeline by means of ArcGIS and its extendable function are probed into. Finally, an example is taken to demonstrate the feasibility and practical application effect.
