FeedMAP
Enabling quick and inexpensive map updates
Up-to-date map data is a must for current and future navigation and Advanced Driver Assistance System (ADAS) applications.
Today, digital maps are normally stored on DVDs or hard disks, with periodic updates only available on replacement disks. However, new mechanisms for updating maps have been investigated and should reach the market within a few years. As the real world is changing every day, detecting changes to the road network quickly and at a low cost is a challenge. Although mapmakers continuously survey the European road network for changes, map information is not always up-to-date or accurate.
In addition to the surveys, mapmakers rely on road authorities and user feedback to detect the latest changes in the road network. The FeedMAP project studies the commercial and technical feasibility of map deviation feedback. In order to improve the flow of user map feedback, the FeedMAP concept uses all vehicles equipped with a digital map for deviation detection, i.e. to check if the maps are indeed accurate and complete.
The project is developing a framework that detects map anomalies when cars happen to come across a faulty map attribute and that quickly updates the maps of all other vehicles using a standardised mechanism for delivering incremental map updates as developed in the ActMAP project.
FeedMAP mainly focuses will be on static and semi-static changes to the road network. In addition, real-time status of reports on events such as traffic jams or accidents can be verified and returned to the information source.
