Abstract
A server arranged to process GPS data to generate enhanced map data is disclosed. The enhanced map data includes a plurality of navigable segments representing segments of a navigable route in an area covered by a map. In at least one embodiment, the server is connected with a wireless telecommunications transceiver arranged to receive GPS fixes by wireless telecommunication from a plurality of navigation devices and send the received GPS fixes to the server, the server includes a processor arranged to generate at least one speed profile for each segment from the GPS fixes from at least two of the plurality of navigation devices, each speed profile comprising an expected speed of travel through the segment, and the server is arranged to subsequently cause the transceiver to send the speed profiles to the navigation devices.
