Abstract
Assessing the accuracy of location estimation systems. A mobile computing device provides location information including a device location (e.g., via GPS) and one or more wireless network beacons accessible by the computing device at the device location. The wireless network beacons accessible by the computing device are compared to stored post information including a plurality of beacon lists. An estimated device location is determined based on the comparison. The estimated device location is compared to the known device location. A difference between the estimated device location and the received device location is determined based on the comparison. An analysis of the determined difference is performed to generate accuracy maps and other insight into the relationship between accuracy and geographic area for the location estimation systems.
