<strong>INTERPOLATION</strong><br />
Kriging<br />
Semi-variance<br />
Where Z i is the measured variable at one point<br />
Z j is another at h distance away<br />
n is the number of pairs that are approximately h distance<br />
apart<br />
Semi-variance may be calculated for any h<br />
When nearby points are similar (Z i -Z j ) is small so the semivariance<br />
is small.<br />
High spatial autocorrelation means points near each other<br />
have similar Z values
