Abstract
Systems and methods to identify a region in which a mobile device is located, by: applying device attributes of the mobile device and region attributes of coordinates of the mobile device to a predictive model to generate an accuracy indicator, identifying a plurality of locations from the coordinates of the mobile device that represent one point and the accuracy indicator, converting coordinates of the locations to cell identifiers of a grid reference system, determining region(s) containing the locations by finding matching cell identifiers that are pre-associated with the region(s), and determining a confidence level of a region that contains at least a portion of the locations based on the weights of locations in the portion. The region is identified in response to a determination that the confidence level is above a threshold.
