kriging - [spatial statistics (use for geostatistics)] An interpolation technique in which the surrounding measured values are weighted to derive a predicted value for an unmeasured location.
developed by Georges Matheron, as the "theory of regionalized variables", and D.G. Krige as an optimal method of interpolation for use in the mining industry ...
Kriging is a group of geostatistical techniques to interpolate the value of a random field (e.g. the elevation Z of the landscape as a function of the geographic location) at an unobserved location from observations of its value at nearby ...

Kriging techniques determine window configuration and weighting factors as a function of the spatial autocorrelation in the sample set.
Of the methods which did not use elevation as ancillary information, was most visually plausible. gave better results than optimal inverse distance when data were anisotropic.
The co-kriging uses beside semivariograms for each variable also cross-variograms for the variable couples. Let us consider the simple case of two variables.
An interpolation technique in which the surrounding measured values are weighted to derive a predicted value for an unmeasured location.
Kriging - A mathematical interpolation method based on the use of a generalized least-squares algorithm. It was first developed for mining applications but is now commonly used for 3-D geographic data processing.
Simple is now the default method; in previous versions, the default was Ordinary . The change was made because of the flexibility of the new Multiplicative Skewing normal score transformation.

Other highly complex interpolation methods exist such as kriging. KrigingA complex geostatistical technique that employs semivariograms to interpolate the values of an input point layer and is more akin to a regression analysis.
This interpolation method is not always appropriate, so there are other methods including Fixed-radius Local Averaging, Inverse Distance Weighted, Trend Surface, Splines, and .
three techniques are Linear interpolation, which effectively runs a straight line between the points with altitude values, the Cubic Spline, which interpolates a smooth curve through the given data points, and Statistical interpolation using Kriging ...
