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.

Landform classification using GIS
by Karsten Drescher, Terralogix Consulting and Willem de Frey, Ekoinfo
