Retail Site Selection tools are powerful data-driven Geographic Information Systems (GIS) purpose-built to define and compare market areas, enabling retailers surveying different sites to view scored results on screen maps. Customizable and scalable down to neighborhoods, informed decisions can be made to open, close, re-brand or re-locate stores based upon local population income, target market, operations costs, economic conditions, area saturation and competition, zone accessibility, zone walking traffic and more. The tools perform advanced analytics that combine the functionality of site mapping with sophisticated geographic, demographic and social data.
