利用地形图生成高程数据方法研究

Research on the method of generating elevation data using terrain map

论述了从地形图中提取等高线、对等高线矢量化以及通过矢量数据生成高程数据的实现方法。在等高线的矢量化过程中,可根据实际需要对采样密度进行控制。实践表明该方法获得了比较满意的效果,在仿真领域中得到了广泛应用。

In this paper,the methods of drawing contour line from terrain map,the vector of contour line and generating elevation data from vector data are discussed.The sampling density can be controlled according to the practical requirement during the course of contour line vector.This method achieves a satisfactory result with experiment and has a wide application area in the simulation system.
