A device receives location information associated with a user of a user device. The location information includes location coordinates associated with the user device over time, and includes errors introduced by one or more location methods used to determine the location information. The device calculates a radius of a geo-location pattern based on the location information, where the geo-location pattern identifies a geographical area encompassing one or more of the location coordinates of the user device. The device calculates center coordinates of the geo-location pattern based on the location information, and determines the geo-location pattern based on the calculated radius and the calculated center coordinates. The device outputs or stores the geo-location pattern.
