Variography

Variography is the analysis of spatial variability of grade within a region. This is an intrinsic part of the estimator functions in Leapfrog Edge. Understanding how sample grades relate to each other in space is a vital step in informing grades in a block model. A variogram is used to quantify this spatial variability between samples. A theoretical variogram is developed as a hypothesis attempting to describe this spatial variability, and experimental variography tools are used to visualise and test this hypothesised variogram
