Take Control

GS+ users have complete control over separation interval classes, one of the most crucial components for creating variograms that accurately represent spatial relationships in your data.

  • Choose constant interval classes or define different breakpoints for every lag class.
  • Create isotropic and any four anisotropic directions simultaneously.
  • Create anisotropic surface maps to identify optimal directionality.
  • All variograms can be scaled to sample variance.

View, Print, Disaggregate

Variograms that appear in the main Semivariance window – both isotropic and anisotropic – can be enlarged into their own windows:

  • Print semivariance values and variograms with or without models.
  • Select any variogram point to examine the data pairs used to create the point.
  • Use variance cloud or h-scattergram analyses to identify outliers.
