Executive Summary

Collaborative spatial decision-making environments in which group members individually and collectively pursue solutions to ill-structured problems have a unique set of cartographic visualization requirements. In this paper the authors restrict the focus to the domain of facility location problems and describe several new map types that are designed to support the process of making comparisons among alternative scenarios. Facility frequency maps depict the stability of sites chosen in a collection of scenarios. Allocation consistency maps show the stability of allocations from demand to supply locations. Alternative forms of these maps are described and examples are presented.
