Abstract
Methods, systems, and articles of manufacture for event-based location sampling for map-matching are provided herein. A method includes determining a location of an object via a device associated with the object; determining one or more temporal sampling periods of one or more location information sensors at one or more sampling regions based on (i) said location of the object and (ii) one or more items of map-matching information; capturing one or more motion-related events associated with the object via the one or more location information sensors during the determined one or more temporal periods; and generating a trajectory of the object based on the one or more captured motion-related events.
