Abstract

In order to present information about a specific position on a map in a mode users can easily understand, a map data processing method includes: identifying a display range of a map; identifying a content and a map element, which are associated with a position within the display range of the map and whose positions are presumed to be identical by using a contents data storage storing position data for each content and a map element data storage storing position data and attribute data for each map element; comparing the attribute data of the identified content with the attribute data of the identified map element stored in the map element data storage; and determining a display mode for the identified content based on a comparison result, and outputting the map within the display range, wherein the map includes display data according to the determined display mode.

Claims

1. A map data processing method, comprising:

identifying a display range of a map;

identifying a content and a map element, which are associated with a position within the identified display range of said map and whose positions are presumed to be identical, by using a contents data storage storing position data for each said content and a map element data storage storing position data and attribute data for each said map element;

comparing said attribute data of the identified content with said attribute data of the identified map element stored in said map element data storage; and

determining a display mode for said identified content based on a comparison result, and outputting said map within said identified display range, wherein said map includes display data according to the determined display mode.

2. The map data processing method as set forth in claim 1, wherein said identifying said content and said map element comprises:

identifying a content associated with a position within said identified display range of said map; and

extracting an map element at a position, which is presumed to be identical with a position of the identified content, from said map element data storage.

3. The map data processing method as set forth in claim 1, wherein said identifying said content and said map element comprises:

identifying a map element associated with a position within said identified display range of said map; and

extracting a content whose position is presumed to be identical with a position of the identified map element, from said content data storage.

4. The map data processing method as set forth in claim 1, wherein said contents data storage stores said content, and said content includes said attribute data.

5. The map data processing method as set forth in claim 1, wherein said contents data storage stores said attribute data for each said content.

6. The map data processing method as set forth in claim 1, wherein said attribute data is data concerning a content type of said content.

7. The map data processing method as set forth in claim 1, wherein, when said comparison result represents inconsistency, said display mode of said content is a mode to emphasize said inconsistency.

8. The map data processing method as set forth in claim 1, wherein, in a destination setting mode in a car navigation system, when said comparison result represents inconsistency, said display mode of said content is a mode that said content is not displayed, and

when said comparison result represent consistency, said display mode of said content is a mode that said content or display data corresponding to said content is displayed.

9. The map data processing method as set forth in claim 1, wherein, in a running mode in a car navigation system, when said comparison result represents inconsistency, said display mode of said content is a mode that said content or display data corresponding to said content is displayed, and

when said comparison result represents consistency, said display mode of said content is a mode that said content is not displayed.

10. The map data processing method as set forth in claim 1, further comprising:

in response to receiving a selection instruction of display data, outputting data concerning said content corresponding to the selected display data and data to explain inconsistency of said comparison result.

11. A map data processing program embodied on a computer-readable storage medium, said program comprising:

identifying a display range of a map;

identifying a content and a map element, which are associated with a position within the identified display range of said map and whose positions are presumed to be identical, by using a contents data storage storing position data for each said content and a map element data storage storing position data and attribute data for each said map element;

comparing said attribute data of the identified content with said attribute data of the identified map element stored in said map element data storage; and

determining a display mode for said identified content based on a comparison result, and outputting said map within said identified display range, wherein said map includes display data according to the determined display mode.

12. A map data processing apparatus, comprising:

a unit that identifies a display range of a map;

a unit that identifies a content and a map element, which are associated with a position within the identified display range of said map and whose positions are presumed to be identical, by using a contents data storage storing position data for each said content and a map element data storage storing position data and attribute data for each said map element;

a unit that compares said attribute data of the identified content with said attribute data of the identified map element stored in said map element data storage; and

a unit that determines a display mode for said identified content based on a comparison result, and outputs said map within said identified display range, wherein said map includes display data according to the determined display mode.
