US Patent 7752069 Computer-implemented method for site selection utilizing weighted bands

After defining a relevant market area around a selected geographical point, a map is generated using stored geographical map information around a selected geographical point and a geographical area is selected around that point. Multiple bands are formed on the map around the geographical point and market information is gathered from a database for the defined geographical area. The bands are weighted based according to empirical data drawn from within the market area, if available, or from data from a demographically matched location. A net demand model is constructed to perform point studies, comparison studies, area studies, and multi-unit simulations for the selected geographical area.
