摘要
20世纪50年代末期DEM技术被提出后,伴随着软件技术的提高与获取数据源手段的不断进步,DEM作为新的技术为公路勘察设计提供了全新高效的方法。本文阐述了基于南方CASS7.1成图系统、Civil3D2006软件、纬地软件平台,通过建立数字高程模型(DEM)对道路设计进行研究,并通过实例进一步阐述DEM技术在道路设计中的优越性。
The 1950s technology proposed DEM along with software technology improvement and progress of data source for means, as new technology DEM, for highway survey and design provides a new efficient method. This paper expounds the CASST. 1 mapping system based on the south, Civil3D 2006 software, software as a platform to weft, by establishing digital elevation model （DEM） on road design, and an example is further elaborates the DEM technology in the design of road superiority.
