Kriging 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.
Kriging Kriging 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  the basis of this technique is the rate at which the variance between points changes over space ...
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 locations.

Kriging techniques determine window configuration and weighting factors as a function of the spatial autocorrelation in the sample set.
6 ~ 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~ uses beside semivariograms for each variable also crossvariograms for the variable couples. Let us consider the simple case of two variables. We have n sample points of the primary variable and m sample points of the single secondary variable (for simple writing we suppose m=n+1).
~ An interpolation technique in which the surrounding measured values are weighted to derive a predicted value for an unmeasured location. Weights are based on the distance between the measured points, the prediction locations, and the overall spatial arrangement among the measured points.
~  A mathematical interpolation method based on the use of a generalized leastsquares algorithm. It was first developed for mining applications but is now commonly used for 3D geographic data processing.

Other highly complex interpolation methods exist such as ~. ~A 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 Fixedradius Local Averaging, Inverse Distance Weighted, Trend Surface, Splines, and ~.
These 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 ~ semivariograms.
