SpatialVariance-class

The spatial variance is estimated by means of Equation 7.16 in <cite>de Gruijter et al., (2006)</cite>.

classes

Spatial coverage sampling and random sampling from compact
geographical strata created by k-means. See Walvoort et al. (2010)
<doi:10.1016/j.cageo.2010.04.005> for details.
