Abstract: Shopper traffic flow is determined based on a filtered set of point of sale (POS) transaction data. A location analytics system determines a presumed best route taken by a customer upon entrance to the store, in walking between each item purchased, and then to the checkout stand. A determination is generated based on filtered parameters to provide visualization of shopper traffic flow in a retail location. Filtered parameters include shoppers for a specific item, or specific brand, to generate a determination as to where those particular shoppers dwelled and experienced impressions. The location analytics server generates visibility into spatial product relationships based on real, POS purchase data, and based on spatial layout data for a given store.
