Maximum Probability of Occurrence

Ideally zonal kriging will yield more definitive results. These maps indicate the maximum probability any particular indicator will occur in any particular cell (not which indicator though). Ideally the two zone model should have fewer low probability cells, and more high probability cells.

Single Zone Two Zone

Here, using two zones (blue) there are fewer low probability cells, more mid-probability cells, and about the same number of high probability cells. This implies that there is less uncertainty in the two zone models which suggests the results are better.
