摘要
使用多项式法对某区域高程异常插值计算,通过对不同参数的实验分析,得到了该区域的最优插值结果的参数;提出了多项式法与反距离加权平均法的综合计算模型,插值计算结果精度比传统多项式法提高了一个数量级。
This paper carried out the interpolating calculation for height anomaly of an area using multinomial method.Through the experimental analysis of different parameters,it acquired the parameters of optimal interpolation results for the area.Then it put forward the integrative calculation model of multinomial method and inverse distance weighting method.Compared with the traditional multinomial method,the accuracy of interpolating calculation results is improved by almost one order of magnitude.
