| 摘 要： | 为促进三维GIS在公路规划、设计、建设与管理等各个阶段的应用,系统地研究了三维GIS与公路CAD的集成方法。首先,针对公路CAD中的路线三维模型与构造物实体模型,分析了三维GIS与公路CAD中数据的集成,进而研究了公路三维GIS的一体化数据组织管理;然后,从三维模型的简化入手,研究了海量数据情况下,公路三维GIS的实时动态可视化技术,并在此基础上,提出了公路三维GIS的体系结构模型;最后,探讨了公路三维GIS在公路路线设计和辅助决策管理等相关方面的应用前景。

| Abstract: | For the purpose of promoting the application of 3-D GIS to the highway plan,design,construction and management,authors presented the integrating methods of 3-D GIS and highway CAD.At first,the data integration of 3-D GIS and highway CAD was analyzed;the 3-D route surface model and the 3D construction solid model were integrated into 3-D highway GIS database.Based on the simplification of the 3-D models,authors discussed the real-time and dynamic visualization technology of 3-D highway GIS in the circumstance of vast database.The architecture of 3-D highway GIS was also presented.Finally,authors discussed the application prospect of 3-D highway GIS for the geometrical route design and the facility management et al. |
