GIS三维可视化技术在天山公路地质灾害评价与决策信息系统中的应用研究

Application and Research of 3D GIS Visualization in Tianshan Highway Geo-hazard Appraisal and Decision Information System

从GIS的三维可视化技术在天山公路地质灾害评价与决策信息系统中的应用研究入手,分析探讨了利用ArcEngine和C#集成方法制作三维可视化界面的关键技术,同时研究了运用ArcEngine集成技术在地质灾害属性查询、地形剖面图分析等一系列过程。分析研究了将二维数据转换为三维数据的技术流程,为实现三维可视化分析和构建三维虚拟现实系统提供了解决方案。研究表明,GIS三维可视化技术与公路地质灾害评价决策结合在一起,能更直观、生动、形象地反映出公路沿线地质灾害情况,为正确的决策支持方案提供科学的依据。

This paper starts with 3D GIS visualization technology in the application of Tianshan highway geo-hazard appraisal and decision information system. It analyzes and discusses the key interface of 3D GIS visualization using the integrate exploitation of ArcEngine and C # and it handles the attribute query in geo-hazard and the analysis of terrain-section chart by using the integrate technology of ArcEngine. Analyzing the technology flow of 2D data to 3D data, it offers the resolve scheme with the 3D visualization analysis and the foundation of 3D VR. It indicates that the combination of 3D GIS visualization technology and highway geo-hazard estimate decision can make circs of highway geo-hazard more intuitively,vivid.visually and can offer the scientific way for the right decision.
