This case study deals with methods of combining multiple maps for empirical modelling in a GIS. Several approaches to analyse multiple maps (Boolean logic models, Binary evidence maps, Index overlay with multi-class maps, and Fuzzy logic method) are introduced by means of a number of basic exercises that follow closely the chapter "Tools for map analysis: multiple maps" from the book Geographic Information Systems for Geoscientists, by Graeme Bonham-Carter (Pergamon,1994, 398 p.). A landfill site selection problem is used as an example.
