安太堡露天矿区的三维地形可视化

The 3D Terrain Visualization of AnTaiBao Opencast Mine Area

为了能够真实地再现安太堡露天矿区的地形特征,以该矿区为研究对象,介绍了对其进行三维可视化的过程。用ArcView GIS软件将该地形的等高线图转换为Grid模型,并导出Grid模型生成ASCⅡ文件,在VC++6.0开发平台中读取ASCⅡ文件里的高程数据并调用OpenGL函数,最终实现三维显示。该方法的实现为露天矿区生态环境问题的研究提供了服务。

For really representing the terrain characteristic of AnTaiBao opencast mine area, 3D visualization of geographic information is introduced with this area for example. It converts the contour line to a grid model by using the ArcView GIS 3.3, and make an ASCII file with the grid model. The elevation data are read in the VC＋＋6.0 development environment from the ASCII file. At the ending, the 3D terrain is manifested by using OpenGL function. This method can serves for the ecological environmental science researchers.
