Users of the system can submit new polygons in return for a credit for their own future access the system. If a user finds that an object reference is inaccurate or wrong, they can submit a new object polygon, which the PROWL system will over-lay with existing data, and then our proprietary code enhances the quality of the overall data. For each unique and valid object a user supplies, they are rewarded with a defined amount of free lookups against the system.
Additionally, through arrangements with third party data sources, even more quality and data can be leveraged.
