Abstract: A navigation apparatus transmits current position information to a server. The server transmits course data to the navigation apparatus; the course data indicates a course that is predicted based on the current position information. The navigation apparatus corrects a subsequently measured current position on the course specified by the course data. The navigation apparatus transmits corrected position information indicating the corrected position to the server. The server distributes map data to the navigation apparatus; the map data corresponds to a specified area containing the corrected position specified by the corrected position information. Based on the received map data, the navigation apparatus displays a map near the corrected position on a screen of a display portion.

Abstract: A curve modeling device includes a curvature calculation unit, a curvature correction unit, and a node information generation unit. The curvature calculation unit calculates a curvature of each sampling point on a route based on location information of each sampling point. The curvature correction unit corrects the curvature at each sampling point and approximates the route by a straight line interval, an arc interval, or a smooth curve interval. The node information generation unit builds a shape model of a curve included in the route by generating node information indicative of a node location on a road corresponding to the route based on the corrected curvature of the sampling point. The curvature correction unit corrects the curvature under a condition that an orientation difference defined by the calculated curvatures maintains a constant value.

Abstract: A destination recommendation system includes a map database storing facility data, a travel history database storing travel history data, a trip destination determination section, a calculation section, a search section, and an output portion. The trip destination determination section determines plural trip destinations corresponding to a hub position when the number or a frequency of a plurality of visits from the hub position to each of the trip destinations satisfies a predetermined condition. The calculation section calculates a distance or necessary travel time from the hub position to each trip destination, and calculates a mode value of the distance or the necessary travel time. The search section searches for a target facility that is located within a range of the mode value of the distance or the necessary travel time. The output portion outputs the target facility to a user.
