ABSTRACT
The field of market analysis has always relied heavily on georeferenced data. While the universe of observation may be postal zones, census enumerator areas, sales territories, marketsheds, and custom trade areas, rather than parcels, utility lines, or watersheds, many of the field's methods and spatial data handling concerns parallel those of municipalities, government agencies, and universities. Burgeoning interest in GIS systems and spatial analysis has been felt in this field and has given rise to numerous efforts to use and adapt this technology to the goals of market analysis.
