基于Kriging方法的空间数据插值研究

Research on spatial data interpolation based on Kriging interpolation

介绍了Kriging插值方法及其实质,提出一种变异函数理论模型参数估计的新方法,给出变异函数理论模型有效性评定的统计指标,并通过算例予以验证。最后,通过实例与反距离加权法相比较,证实Kriging插值的优越性。

This paper introduces interpolation method of Kriging and its essence, advances a new method to the parameter estimate of variogram theory model, and this method gives some statistic criterias that proved by the example. At last, another example proves the advantages of Kriging interpolation compared with inverse distance to a power.
