Fuzzy logic: Identifying areas for mineral development

by Mandy Vickers and Gavin Fleming, Mintek

This article looks at the application of fuzzy logic set theory in GIS to identify potential areas for mineral development. Arc-SDM (Spatial Data Modeller) was used to assign fuzzy membership values to the selected criteria and calculate a combined output surface indicating the potential of areas for gold mineral development based on fuzzy set membership. Arc-SDM is a software extension for ArcMap that provides additional geo-processing and modeling functionality, including fuzzy logic tools for geological and mineral applications.
