 Fuzzy images:                                           back

Before any decision analyses are run, all eight (12 themes – 4 themes (basemap) = 8) criteria are needed to convert to distance images.  Then these distance images were run as input file for fuzzy images.  In addition, three different weight modules were created for the purpose of inputting varies importance of each categories.  The three categories used three different combinations of weight module and fuzzy images to run the MCE function in Idrisi.  The images came out are the presented in Spatial Analysis.
