Take a typical region in the Loess Plateau of North Shaanxi Province zone as the study area.Based on relief map with a scale of 1:1000 to generate accurate 3D ter ain DEM using Anudem algorithm. Compared with the production the precision of Anudem method and TIN method between DEM. DEM accuracy evaluation including value target, slope, contour line playbacking and different differential value algorithm result variance analysis. The DEM dif erence that DEM precision of Anudem method production is best, can very good response precise three-dimensional ter ain.
