Mõnikord koostatakse esimese sammuna poolhajuvusväli (ingl semivariogram cloud), kus iga vaatluspunkti paar (omavahelise kaugusega hkl) kajastub γ ja h teljestikus omaette punktina: γkl = ½ (xk − xl)2.
To create an empirical semivariogram, determine the squared difference between the values for all pairs of locations. When these are plotted, with half the squared difference on the y-axis and the distance that separates the locations on the x-axis, it is called the semivariogram cloud.
