Zusammenfassung:	A method of processing positioning data to create map data is disclosed, the map data including a plurality of navigable segments representing segments of a navigable route in the area covered by the map with each segment being arranged to have speed data associated therewith. In at least one embodiment, the method includes processing the speed data to categorise the speed data into a plurality of time periods for the navigable segment with which the speed data is associated; and averaging the speed data within each time period in order to generate a measured speed profile for the navigable segment.
