Mapping Spatial Distributions
…the geo-registered soil
samples form a pattern of
“spikes” throughout the
field.  Spatial
Interpolation is similar to
throwing a blanket over
the spikes that conforms
to the pattern.
…all interpolation algorithms assume
that 1) “nearby things are more alike
than distant things” (spatial
autocorrelation), 2) appropriate
sampling intensity, and 3) suitable
sampling pattern.
…the continuous surfaces produced map
the spatial distribution of the samples.
