用数模方法获取纸上移线后横断面地面线

Using Method of DTM to Get Cross Section Ground Line after Alignment Moving on Paper

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．

In the process of highway surveying and designing,it is often 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 designers.In this paper,a method of DTM(Digital Terrain Model) is given.
