介绍了数字测绘成套技术的发展现状及其技术理论,结合四川绵竹至茂县公路项目,讨论了如何将数字测绘成套技术应用于公路勘察设计以及如何利用该技术实现三维地表数据获取、建模、动态设计、景观实时动态漫游以及方案比选和优化。通过与传统勘测手段的对比,分析了数字测绘成套技术的社会和经济效益,以及该技术对于提高公路勘察设计质量的显著作用。
This paper introduces the development status and technical theory of the complete set of digital surveying and mapping techniques and the Mianzhu-Maoxian highway project in Sichuan province. It discusses how to apply the complete set of digital surveying and mapping technologies to the road survey and design and how to use this technology to acquire 3D surface data, Design, landscape real-time dynamic roaming and program comparison and optimization. By comparing with the traditional surveying methods, this paper analyzes the social and economic benefits of the complete set of digital surveying and mapping techniques and the significant role of this technology in improving the quality of highway survey and design.
