基于矢量化地形图的公路纸上定线自动化实现技术

针对传统纸上定线方法效率低及制约公路多方案比选的问题,对道路设计的内、外业工作进行分析,研究矢量化地形图构建数字地面模型DTM的方法,提出应用纬地道路CAD软件的数模DTM功能实现电脑桌面定线的自动化技术。结果表明该技术可实现数据采集、路线设计、设计绘图、方案优化一体化等功能,缩短道路勘测及设计周期,全面提高设计质量。

Based on the Vector Topographic Map of the Road Paper Alignment Automation Technique

In view of the traditional paper location methods is low efficiency and restricting highway multiple selection problem, the road design, work outside the industry are analyzed, the research on vector topographic map of constructing digital terrain model of DTM method, proposes the application of latitude road CAD software module DTM function realization of desktop computer alignment automation technology. The application results show that： this technology can realize the data acquisition, route design, graphics design, scheme optimization integration, shorten the design cycle, road survey, improve design quality.
