The next logical step is for a private drone company with the ability to collect, and analyse this data in near real time and sell it to Wall Street. Maybe even sell the data to WalMart so they can monitor staffing levels, and have the right amount of staff on the tills at all times for maximum throughput. You could also monitor shipping at ports, rail yard delivery volume, trucks at warehouses and so on.
