| 摘 要： | 在"包头市人工影响天气综合业务系统"中以1:5万的数字高程模型(DEM)为基础,将图像平面与三维地形叠加,采用三维场景的模拟方法绘制包头地形图,其核心是三维地形的可视化显示。三维地形可视化通常采用DEM作为基础地理数据,在上面叠加遥感影像,这就保证了三维模型能够较为真实地反映实际的场景。

| Abstract: | Based on the digital elevation model （DEM） by 1：50,000, the system simulates the topographic map of Baotou, combining the image plane with the three dimensional terrain superimposition using the three- dimensional simulation, which core is the display of the visualization of the three-dimensional terrain. The visualization of the three-dimensional terrain uses DEM as a foundation and superimposes on top the remote sensing images, which ensures a more realistic three-dimensional model can reflect the actural scene. |
