Kriging uses the following equation to calculate interpolated values. $z_{0}=\sum_{i=1}^{k} z_{i} w_{i}$ The weight w_i depends on A) a fitted curve to the semivariogram constructed with the sampled points B) the distance to the prediction location from the neighbouring sampled points C) the spatial correlation between the sampled points and the prediction location D) all the above

Question

Quizplus · Accepted Answer

The weight calculation in Kriging depends on all the above factors. The semivariogram is used to quantify the spatial correlation between the sampled points, and the distance to the prediction location determines the "closeness" of the neighbouring sampled points. Therefore, all the given options are necessary in calculating the weight and, ultimately, the interpolated value.
