Applying the model to the four factor databases the overlay
operation was digitally performed to create the map units that were
subsequently assigned to the soil salinity potential class as defined. In
the process of the formulation of the model the iterations were made
to adjust the conditions being highly correlated the geo-referenced
ground truth and the existing salt crust maps. The schematic of map
overlaying of salinization factors as shown in figure 2 in which the
soil salinity potential map was created.
