Abstract
A method for updating a geographic database containing image data and road vector data to be used in vehicle navigation systems includes determining whether a vehicle is in an on-road position based on information provided by the vehicle navigation system. A geographically coded image is generated with a vehicle-mounted camera if the vehicle is not in an on-road position according to the information provided by the vehicle navigation system. The geographically coded image generated by the vehicle-mounted camera is analyzed in order to determine whether the geographic database requires updating.
