Next,
fuzzy layers need to be derived from the data collected. This would provide
a suitability value that cannot be obtained from the constraint layer. While
constraint factors show where Cheetahs can and can't live it fails to show the
better place to live. All fuzzy layers were derived from layers that were previously
distance layers. In the analysis it is crucial that the distance from potential
disturbances measured. The further away from the disturbances the more suitable
the site. The exceptions are the parks close fuzzy and parks fuzzy layer. These
particular layers were developed in order to provide two opposite circumstances.
There isn't only one possibility when analyzing. Here is where parks fuzzy define
distance from parks as being positive. Parks close fuzzy is a layer were the
closer the area to a park the higher the suitability. There were two major analysis
made where these were the differing factors.
Once the layers were prepared for the Multi-Criteria Evaluation they had
to be weighted. Not all factors are as important as the next. Using the Weighted
Linear Combination did this. Some factors impact landscape and animals at
different rates as well, in different ways. An example from this project is
deciding weather or not overgrazing is more important than population density.
It seems obvious that there can be overgrazing without high population densities.
On the other hand high population densities will most likely cause overgrazing
to occur. Therefore, population density would be weighted with a higher number
than overgrazing because of its higher relative importance. The Pairwise Table
determines these weight values. The Relative importance of the suitability
factors use in the MCEWLC analysis is assessed. The weights are given in the
interactive cartographic model.

darker green represents a higher suitability based on the criteria outlined
in the cartographic model.
