Abstract: In the process of highway surveying and designing, it is of ten required to make alignment moving on paper, After the moving, how to get the cross section ground line quickly and accurately is important, so it is a concern of the desig ners. In this paper, a method of DTM (Digital Terrain Model) is given.

Key words: DTM(Digital Terrain Model), alignment moving on paper, ground line, insert

摘要： 结合数字地面模型的处理方法提出了一种利用数模方法快速获取移线后横断面地面线的新方法.
