1.2 Simple Exponential Model Kriging. Kriging is a geostatistical interpolation technique that considers both distance and the degree of variation between known A variogram is often defined as a measure of spatial variability. Sampling for points close to each other produces typically similar outcomes
The variogram is a simple tool for analyzing spatial variability. WinGslib is toolbox of Geostatistical software algorithms written for Windows When properly understood, the VARIOGRAM will allow the determination of adequate sample spacing, and provide the model parameters required for kriging.

Takes readers through the essential steps in computing and modelling the variogram, which is often done in a black-box environment that does not lead to an understanding of the spatial variation. Short computer code to guide users in GenStat as a learning medium.
Function for simple, ordinary or universal kriging (sometimes called external drift kriging), kriging in a local neighbourhood, point kriging or kriging of block mean variogram model of dependent variable (or its residuals), defined by a call to vgm or fit.variogram; for krige0 also a user-supplied covariance
Fixed rank kriging (FRK) is a spatial/spatio-temporal modelling and prediction framework that is scaleable, works well with large datasets, and can deal easily with data that have In Section 3, we discuss further details of the package and provide a simple example on the classic meuse dataset.

Types of Kriging. Assume a covariance function ?(s, s ) on the space. • Simple kriging: yi = i. • Ordinary kriging: yi = µ + i. • Universal kriging: yi = xTi ? + i. In the case of ordinary kriging, estimating the variogram doesn’t require an estimate of the mean, unlike estimating the covariance.
Kriging relies on the semi-variogram. In simple terms, semivariograms quantify autocorrelation because it graphs out the variance of all pairs of data according to distance. Chances are that closer things are more related and have small semi-variance.
