distributed deposit, where no variograms could be produced. With lognormally
distributed data often found in ore resources, having a good variogram is
important, to avoid large errors in kriging hence it may be preferential to use
IDW and a topcut. However if your data is not so highly skewed even approximating
a variogram can provide superior results. I used to model topography surfaces
and Kriging with a 'guessed' variogram produced good results compared to
IDW which produced highly spiked and erroneous results.
