Automatic relocation of link related data in an updated road map

Kurzfassung

For a rising number of ITS applications, location information obtained by the processing of sensor data is related to the links of a specific digital road map. Such maps are available from different vendors like Here, TomTom/TeleAtlas and OSM. They are created with different philosophies, resulting in significant differences in the geometry and the topology of the road networks. If a map needs to be updated to a new release, the user faces the problem that a relocation of any annotated location data, i.e. a proper mapping of these locations from the old to the new map becomes necessary. For this reason, DLR developed a new prototypic software application called DataRelocator@Map2Map. It enables the automatic relocation of location data between the two maps. Using this new tool, an almost fully automatic relocation is possible and thus the cost of service failures related to the map update can be avoided.
