Abstract
Systems, methods, and programs store feature information relating to features existing on a road and on the periphery of the road, each piece of feature information being associated with a unique identification symbol, each piece of feature information including disposition information expressing a spatial disposition of each feature independently of the road network, form information expressing a form of each feature, accuracy information expressing an accuracy of the information, and acquisition timing information expressing an acquisition timing of the information. The systems, methods, and programs (1) output the feature information stored in the feature database and input map information constituting the map database, the map information being generated based on the output feature information, or (2) generate map information constituting the map database on the basis of the feature information stored in the feature database.
