随着计算机科学的发展和各种测量高新技术的不断出现,公路勘测设计方法得到了迅速发展。文章以高新技术测量为主体的野外勘察,以DTM(数字地面模型)为基础的内业数据处理,越来越多的集成到公路计算机辅助设计软件中,方便设计人员利用数字地面模型分析计算得到各种需要的数据,从而形成公路设计全过程的设计一体化技术。 With the development of computer science and the emergence of various high and new measurement technologies, the highway survey and design method has been rapidly developed. The article takes the high-tech surveying as the main field survey, and the DTM (Digital Terrain Model) -based internal data processing is more and more integrated into the highway CAD software to facilitate the designers to analyze and calculate with the digital terrain model Various needs of the data, thus forming the whole process of highway design integration technology.
