`Geographic Projection of Cluster Composites'

Abstract

A composite cluster map displays a fuzzy categorisation of geographic areas. It combines information from several sources to provide a visualisation of the significance of cluster borders. The basic technique renders the chance that two neighbouring locations are members of different clusters as the darkness of the border that is drawn between those two locations. Adding noise to the clustering process is one way to obtain an estimate about how fixed a border is. We verify the reliability of our technique by comparing a composite cluster map with results obtained using multi-dimensional scaling.
