基于3S技术的丹东市帽盔山三维地形可视化

3D Terrain Visualization of Maokui Hill in Dandong City Based on 3S Technology

文章以丹东市帽盔山1∶10000地形图为基础,在ArcGIS软件中建立其DEM,结合高空间分辨率遥感卫星QuickBird的正射影像作为三维表面的纹理信息,通过二者的叠加,在ERDAS IMAGINE软件中实现了研究区域的三维地形立体显示。

Based on the topographic map of Maokui mountain in Dandong city（a scale from one to ten thousand）,the DEM of the hill was built with ArcGIS.Besides,the texture information of tridimensional surface of the hill was gotten from the orthophotomap of QuickBird got from remote sensing satellite with a high spatial resolution.With ERDAS IMAGINE,the stereoscopic display of tridimensional topography of the hill was realized.
