inverse distance interpolation

基本解释

Established the landform model by distance power inverse ratio method and fractal interpolation algorithm.
利用距离幂反比法加分形插值算法建立了地形模型。
Using the areal weighting interpolation and inverse distance weighted averaging, a spatial distribution model of GDP is established in this paper.
文章采用栅格数据模型，运用面积权重法和反距离加权法对GDP值进行了空间拓展。
Inverse distance interpolation can produce a totally precise result, but in area such as valley or peak of a mountain, it will induce considerable error.
距离倒数插值从整体上保证了插值结果的准确度，但在局部地形突变的区域误差较大。基于最小二乘思想的线性拟合方法能弥补这一不足。
