Imagine that there is a drainage basin made up of five rain gauges, as is the case
in Figure 7.15; we assume that the correlogram takes the following form:

values it is possible to create detailed maps similar to the one that can be seen in
Figure 7.15.

From Figure 7.15, it can be seen that the isovalue curves are focused around the
rain gauges and that the distribution of the grid points, which are part of the
Thiessen polygons, are also coherent.
