RECONSTRUCTING ROUTES USING ELECTRONIC MAP DATA
First Claim
1. A method of reconstructing a route through a navigable network in an area covered by an electronic map, the electronic map comprising a plurality of segments representing navigable segments of the navigable network, the method comprising:
- obtaining data indicative of a polyline representative of a route through the navigable network, which route is to be reconstructed in relation to the electronic map; and
using the obtained data indicative of the polyline in generating a route through the navigable network as represented by the electronic map, wherein the generated route provides a reconstruction of the route represented by the polyline through the navigable network in relation to the electronic map, and wherein the generating of the route comprises favouring segments of the electronic map for inclusion in the generated route that are in greater proximity to the polyline as represented on the electronic map.

Abstract
A navigation device (300) transmits data indicative of an origin and destination of a desired route through a navigable network to a server. The server (310) generates a recommended route and provides data indicative of the route to a system (320) which provides a polyline representative of the route. The polyline is provided to the navigation device (300), which uses the polyline data to reconstruct the route. The navigation device (300) determines a least cost route through the network using the polyline data in order to reconstruct the route in respect to its own electronic map data. This is done by penalising segments depending upon their distance from the polyline, such that segments further from the polyline are less likely to be included in the route.

19. A routing system for reconstructing a route through a navigable network in an area covered by an electronic map, the electronic map comprising a plurality of segments representing navigable segments of the navigable network, the system comprising:
-
a processor; a memory, wherein the memory stores the electronic map; wherein the processor is operable to; obtain data indicative of a polyline representative of a route through the navigable network, which route is to be reconstructed in relation to the electronic map; and use the obtained data indicative of the polyline in generating a route through the navigable network as represented by the electronic map, wherein the generated route provides a reconstruction of the route represented by the polyline in relation to the electronic map, and wherein the generating of the route comprises favouring segments of the electronic map for inclusion in the generated route that are in greater proximity to the polyline as represented on the electronic map.

23. A non-transitory computer readable medium which stores a set of instructions which when executed performs a method for reconstructing a route through a navigable network in an area covered by an electronic map, the electronic map comprising a plurality of segments representing navigable segments of the navigable network, comprising:
-
obtaining data indicative of a polyline representative of a route through the navigable network, which route is to be reconstructed in relation to the electronic map; and using the obtained data indicative of the polyline in generating a route through the navigable network as represented by the electronic map, wherein the generated route provides a reconstruction of the route represented by the polyline through the navigable network in relation to the electronic map, and wherein the generating of the route comprises favouring segments of the electronic map for inclusion in the generated route that are in greater proximity to the polyline as represented on the electronic map.
