One of these approaches is the creation of  a geomarketing system with a fundamentally new toolkit based on data  clustering. The capabilities of such a system are shown using examples of  housing cost assessment, determining the location of a new shopping center, a  bank branch and a clinic. P. 180–187 | |||||||||
