Spatial Analysis
One constraint was used in the multi-criteria evaluation and seven factors. The one constraint was simply derived from the land use file by reclassing water bodies and lakes that are should not be considered. The seven factors were then converted into fuzzy images using the decision wizard with the following parameters.
