The digital elevation model(DEM) is not only the geographic phenomenon's simulating expression and the process simulation of the continuously change character in the two-dimensional geographic space,but also a set which is a spatial continuously fluctuant phenomenon's digital expression and an analytic tool.The road engineering is the earliest field which DEM is employed in.In the road survey and design process,DEM can be carried on the plane,the longitudinal section,the cross section automatic production,the equalization of earthwork alternately with mixes,and the path multi-plans compared to elects.It also can realize the path landscape model and the animation demonstration by the design surface model and DEM superimposition.Thus DEM can make evaluations on the design quality,and analyzes the harmonious situation between the building road and surrounding.
