Criteria Weights and Map Scores
To determine the relative importance or
weights of each individual class with another in each thematic map six
importance matrices were prepared by pairwise comparison on Satty’s
importance scale. These matrices have the property of consistency known as
consistency ratios (CR). Satty indicates that the matrices with CR ratings
greater than 0.1 should be re-evaluated. This way it helps to analyse the matrix
to determine the inconsistency in defining the interrelationships. The above
method was applied to the six matrices to evaluate the individual class weights.
These weights were normalised by multiplying with 100 to avoid complexities of
computation. The importance matrices and their weights are as
follows:

All individual class weights were multiplied
with map scores and kept in linear summation equation to result in a unified
weight map. This map was classified to get five potential zones from excellent
to poor (Fig. 8).
