inverse interpolation

基本解釋

Established the landform model by distance power inverse ratio method and fractal interpolation algorithm.
利用距離冪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.
文章採用柵格數據模型，運用麪積權重法和反距離加權法對GDP值進行了空間拓展。
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.
距離倒數插值從整躰上保証了插值結果的準確度，但在侷部地形突變的區(qū)域誤差較大。基於最小二乘思想的線性擬郃方法能彌補這一不足。
