摘要
文章提出了一种采用等高线生成数字高程模型的算法:动态网格模板法(DGT),并采用C++语言编程实现了算法.该算法采用动态网格模板确定最近邻域,并使用加权距离平均值计算代替复杂的误差方程求解过程,具有较高的内插效率.
This article presents an algorithm of building DEM based on dynamic grid template.And this algorithm is realized with C＋＋ language.In this algorithm, nearest neighbor is located with dynamic grid tem- plate, and complicated computation of simultaneous error equations is substituted for applying the average of distance with weight.The test proves that the interpolation efficiency is ideal.
