Eesliide „semi-“ (pool-) tuleneb kordajast ½ γ(h) arvutusvalemis. See ½ on tingitud asjaolust, et dispersiooni leidmisel on formaalne vaatluspaaride arv – n punkti korral n(n–1) – kaks korda suurem sisulisest (pole ju vaja eristada kaugusi Ast Bni ja Bst Ani).
Semivariogrammid kui erinevate nähtuste ruumiliste omaduste visualiseerimisviis pakuvad spetsialistidele ka iseseisvat huvi, kuid nende peamiseks rolliks on, et semivariogrammide alusel pannakse paika geostatistilise modelleerimise olulisi parameetreid.
An expected elevational distance is measured with the use of a statistical graphing technique called the semivariogram, which plots the distance between samples, called the lag, on the horizontal axis, the vertical axis gives the semivariance, which is defined as half the variance (square of the standard deviation) between each elevational value and each of its neighbors.
