Navigation apparatus and navigation processing method
First Claim
1. A navigation apparatus, comprising:
- a map data obtaining unit that obtains map data;
a navigation processing unit that executes navigation processing by using the map data having been obtained;
a search data obtaining unit that obtains search data;
a specific data detection unit that detects specific data for a specified search target by using the search data having been obtained;
a correspondence table obtaining unit that obtains a correspondence table indicating correspondence between identification information used to identify individual road units into which each road is divided in predetermined units and map data road unit information related to map data road units defined in the map data individually corresponding to the road units; and
a map position determining unit that determines a position of the specified search target in the map data based upon the specific data for the specified search target having been detected and the correspondence table having been obtained, wherein;
the identification information includes road inherent information assigned permanently to each road unit to identify each road unit;
the specific data corresponding to each of various search targets, which are included in the search data, contain the identification information used to identify a road unit at which the search target is located; and
the map position determining unit obtains the map data road unit information from the correspondence table having been obtained, which corresponds to the identification information contained in the specific data for the specified search target having been detected, and identifies the map data road unit in the map data based upon the map data road unit information having been obtained.

3. A navigation processing method comprising:
-
obtaining search data; obtaining map data; detecting specific data for a specified search target by using the search data having been obtained; establishing a correspondence between the search data and the map data by using a correspondence table indicating correspondence between identification information used to identify individual road units into which each road is divided in predetermined units and map data road unit information related to map data road units defined in the map data individually corresponding to the road units; and executing navigation processing by using the search data having been obtained, the map data having been obtained, and the correspondence having been established, wherein; the identification information includes road inherent information assigned permanently to each road unit to identify each road unit; the specific data corresponding to each of various search targets, which are included in the search data, contain the identification information used to identify a road unit at which the search target is located; the map data road unit information, which corresponds to the identification information contained in the specific data for the specified search target having been detected, is obtained from the correspondence table; and the map data road unit is identified in the map data based upon the map data road unit information having been obtained. - View Dependent Claims (10)
