Topics in interpolation and smoothing of spatial data
… inappropriate in certain respects. The semi-variogram plays a central role in geostatistical work. In both of the applications considered here, the raw semi-variogram is 'contaminated' by error, but the error variance varies widely between data points, so that the spatial autocorrelation …

Surface forcing of the North Atlantic: accuracy and variability
… in<br/>terms of random errors using a semi-variogram analysis and a range of variogram<br/>models. The data quality and sampling are then taken into account using optimal<br/>interpolation (OI) to grid the observations, producing daily mean fields and uncertainty<br/>estimates. These …

Spatial variability of hydraulic properties as affected by physical properties of selected soil types in South Africa
… 10.4 to generate spatial variability maps and semi variograms. The University of Venda Experimental farm had lesser spatial variability with coefficient of variation ranging from 9.6 to 33.4%. The spatial variability of soil was very low confirmed by contour maps depicting slightly homogeneity. …

The use of fractal dimension for texture-based enhancement of aeromagnetic data.
… methods (1D and 2D Hurst methods and 1D and 2D semi-variogram methods), and; • spectral methods (1D and 2D wavelet methods and 1D and 2D Gabor methods). All of these methods are able to differentiate between varying theoretical FD in synthetic profiles. Moreover, these methods are able to …
