摘要
文中分析了常用的插值方法 ,通过对等高线生成DEM数据方法的研究 ,提出了分量内插方法生成DEM数据的算法 ,对实现过程进行了详细分析 ,并对DEM网格精度作了进一步探讨 ,该算法已用VC + + 6 .0编程实现。通过实际使用 ,证明该算法执行速度快 。
This paper analyzed method of interpolation in common use, and bring up the weight interpolation algorithm to make DEM data through to research contour line in maps method of born DEM data. It analysis realized the process in detail, and study the accuracy to make DEM mesh in further. That algorithm has already realized by the VC++6.0 programming. It has been proofed that algorithm carry out the speed quick and can satisfy the accuracy request, is a practical algorithm by actual usage.
