Claim 15:
16. A first system for guiding a vehicle along a first route on a first map of the first system based on a second route on a second map of a second system, wherein the first system comprises a geographical positioning device, and wherein the first map and the second map comprise path networks in the area of the vehicle, the first system comprising a processor to:
receive the second route on the second map from the second system, wherein the second route is a predetermined polyline through the path network of the second map from a starting point to a destination point, the predetermined polyline further comprising a plurality of second points on the path network of the second map between the starting point and the destination point;
select support points on the second map,
wherein the support points comprise a subset of the plurality of second points of the second route;

determine first points on the first map;
wherein the first points correspond in pairs to the support points;

determine the first route, wherein the first route forms a polyline through the path network of the first map from the starting point to the destination point, the polyline further comprising the first points between the starting point and the destination point,
characterized in that the first route is determined by means of trace matching based on a geometric similarity to the second route;

obtain a current position of the vehicle from the geographical positioning device; and
guide the vehicle along the first route in relation to the current position.
