1. A method comprising: receiving sensor data collected by one or more sensors of a computing device and a timestamp indicative of a time at which the sensor data was collected by the one or more sensors of the computing device; receiving a history of geographic locations of the computing device determined based on the sensor data collected by the computing device and additional data from one or more sources; receiving updated additional data from the one or more sources, wherein the updated additional data corresponds to (i) updated position data of wireless nodes associated with the time at which the sensor data was collected by the one or more sensors of the computing device or (ii) updated location information associated with a location at which the sensor data was collected by the one or more sensors of the computing device; reprocessing at least a portion of the sensor data with the updated additional data to determine one or more updates to the history of geographic locations of the computing device; and modifying the history of geographic locations of the computing device based on the one or more updates to provide an updated history of geographic locations of the computing device.
