Method for data transmission route.

Method for transmitting at least route data (40) from a central to a terminal unit, in particular a navigation system for vehicles, where the route data (40) relate to at least one path route having a starting point of the route corridor (1) and a destination point of route corridor (6), wherein the route data (40) comprise data benchmarks path (44-46), that relate to the reference points (1-10) which lie between the starting point of the route corridor (1) and the destination of the route corridor (6), wherein two adjacent reference points are connected by a path, and the starting point of the route corridor (1) and the destination of the route corridor (6) also comprise a respective reference point (1,6), and wherein the data points reference (44-46), along with the attributes of the corresponding reference point (01/10) comprise attributes of paths that deviate from the respective reference points (1-10), characterized in that the data reference points (44-46) for reference points that are at the beginning of the route corridor are to be transmitted first place, and because it is assumed at least the next waypoint is defined by the following data (44-46) transmitted landmarks, in the case that the data (44-46) landmarks do not contain features relating to the next reference point (01/10).
