Dakota Aquifer Program--Geologic Framework
Hodgeman County Study, part 10 of 12
Mapping of group membership probabilities.
Figure 7 shows the continuous variation for all membership
probabilities across the study area. Table 5 contains the
semivariogram models and Figure 8 displays both the models and
the experimental semivariograms. To minimize extrapolation
outside the convex hull of the sampling, estimates exceeding
certain kriging variance threshold were ignored. From top to
bottom and from left to right such maximum variance values for
the maps in Figure 7 are 0.13, 0.055, 0.16, 0.235, 0.235.
