AI-GEOSTATS: kriging variance as a function of sampling density

[Kerry Ritter]

Hi.  I am looking for a simple way to compute the kriging variance as a 
function of distance between sampling sites for a given spherical and 
exponential semivariogram.  I know that these variances do not depend on 
the data values, but on location.  Thus, it seems like this would be a 
common enough task where one would use this curve for completing a 
cost-efficiency analyzes with regard to sample spacing.  I currently use 
Splus/R.

Thaniks,
Kerry
