Fuzzy logic is a form of multi-valued logic derived from fuzzy set theory to deal with reasoning that is approximate rather than precise in contrast with binary sets having binary logic, also known as crisp logic, the fuzzy logic variables may have a membership value of not only 0 or 1just as in fuzzy set theory with fuzzy logic the set membership values can range (inclusively) between 0 and. Fuzzy concepts in gis. The fuzzy overlay tool allows the analysis of the possibility of a phenomenon belonging to multiple sets in a multicriteria overlay analysis not only does fuzzy overlay determine what sets the phenomenon is possibly a member of, it also analyzes the relationships between the membership of the multiple sets the overlay type lists the methods available to combine the data based on set theory.
Fuzzy Concepts in GIS
1 example: fuzzy site analysis fuzzy concepts slope is considered flat when it is below 10 degrees both cases were computed using the model builder in arcgis 9 for the fuzzy case a tool written as a python script to create a fuzzy set was used. The deployment of fuzzy set theory and fuzzy logic for spatial applications and spatial analysis methods has gained increasing popularity in the geoscience and gis communities and also led to a large amount of literature on fuzzy approaches in the gis domain. a spatial concept is vague or fuzzy if locations exist that.
