| 摘 要： | 以昆明市为例，利用1：50000纸质地形图在ArcGIS中完成等高线矢量化，并在ERDAS中建立高精度的DEM数据。再采用ETM＋影像制作的昆明市正射影像作为三维表面的纹理信息，应用ERDAS IMAGINE8．7的VirtualGIS模块，在相同的投影坐标系统下，将数字高程模型（DEM）数据与遥感正射影像进行叠加实现了昆明市的三维地形可视化。

| Abstract: | As an example for Kunming City,using papery topographic map,contour line was made in ArcGIS,and then high precision DEM data was created in ERDAS.Based on texture information of the 3D surface from ETM+ Image,using the ERDAS IMAGINE 8.7's module of VirtualGIS,orthographic and DEM data were overlapped to create three-dimensional terrain modeling and visualization of Kunming in the same projection reference frame. |
