Abstract

A method includes obtaining a first geo-location and a second geo-location. The first and second geo-locations are associated with a monitoring device. The monitoring device is configured to be used by a user. The first geo-location is determined at a first time and the second geo-location is determined at a second time. The first time and the second time are associated with a rate of obtaining geo-location data. The method includes calculating a difference in distance between the second and first geo-locations and changing the rate of obtaining a third geo-location associated with the monitoring device based on the difference in distance between the second and first geo-locations.
