Dear All,
The range obtained from fitting an exponential function to empirical
variogram using gstat library of R is 5.5 m. This indicates that the
practical range is  5.5 x 3 = 16.5 m indicating a pair of sample yield
points whose distance is beyond 16.5 m is uncorrelated.

what will be the value of maxdist option of krige function to produce
estimated values within the grid? I thought of using maxdist=16.5 as my
search radius in interpolation so that a data point beyond 16.5 m will not
be used in interpolation. Am I right to use the practical range (16.5) or
the original range (5.5) obtained directly from fitting the exponential
model?

Thank you.
