| Abstract: | The authors introduced the manners and flow sheet of collecting high precision DEM with the help of remote sensing technologies such as LiDAR, synthetic aperture radar and photographic surveying. DEM was widely applied in the fields of geology, landforms, land and national defense construction. The authors conducted test and discussions on terrain monitoring by high precision DEM, contrasted DEM image display effect of different resolutions （ 1, 10, 30 m）, concluded the advantages of high precision DEM in the fields of display and analysis. Through calculation of the shadow of the mountain, slope and terrain curvature, the authors realized the study of different terrain monitoring methods based on high precision DEM of single stage. |
