Device and method for changing map information
First Claim
1. A map information changing device for changing positions of landmarks and areas included in map information, said device comprising:
- map information storage means for storing said map information at least related to roads, the landmarks, and the areas;
overlap determination means for determining whether the landmark and the area included in said map information overlap with the road included in said map information and displayed with a road width;
position change means for changing positional information of the landmark and the area determined by said overlap determination means as overlapping with one or more roads by moving each of the landmark and the area to a position at which each of the landmark and the area does not overlap with said one or more roads displayed with the road width, while keeping a location side of each of the landmark and the area with respect to a center line of each road; and
changed map information storage means for storing said map information and the positional information of the landmark and the area changed by said position change means.

Abstract
A map information storage 10 stores map information including roads, landmarks, and areas. An overlap determination unit 11a determines whether a landmark and an area overlap with a road in consideration of a road and its width. A position changer 12 moves the overlapping landmark and area to positions at which they do not overlap with the road on width display. A changed map information storage 13 stores map information including changed positional information of the landmarks and the areas. If the changed map information is displayed on a screen, the landmarks and the areas are displayed so as not to overlap with roads on width display.

9. A method for changing positions of landmarks and areas included in map information, said method comprising the steps of:
-
storing said map information at least related to roads, the landmarks, and the areas;
determining whether the landmark and the area included in said map information overlap with the road included in said map information and displayed with a road width;
changing positional information of the landmark and the area determined in said overlap determining step as overlapping with one or more roads by moving each of the landmark and the area to a position at which each of the landmark and the area does not overlap with said one or more roads displayed with the road width, while keeping a location side of each of the landmark and the area with respect to a center line of each road; and
storing said map information and the positional information of the landmark and the area changed in said positional information changing step. - View Dependent Claims (10, 11, 13)

14. A map information changing device for changing positions of roads included in map information, said device comprising:
-
map information storage means for storing said map information at least related to the roads, landmarks, and areas;
overlap determination means for determining whether the road included in said map information and displayed with a road width overlaps with the landmark and the area included in said map information;
position change means for changing positional information of the road determined by said overlap determination means as overlapping with one or more landmarks and areas by moving the road displayed with the road width to a position at which the road does not overlap with said one or more landmarks and areas, while keeping a location side of each of the landmarks and the areas with respect to a center line of the road; and
changed map information storage means for storing said map information and the positional information of the road changed by said position change means. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for changing positions of roads included in map information, said method comprising the steps of:
-
storing said map information at least related to the roads, landmarks, and areas;
determining whether the road included in said map information and displayed with a road width overlaps with the landmark and the area included in said map information;
changing positional information of the road determined in said overlap determining step as overlapping with one or more landmarks and areas by moving the road displayed with the road width to a position at which the road does not overlap with said one or more landmarks and areas, while keeping a location side of each of the landmarks and the areas with respect to a center line of the road; and
storing said map information and the positional information of the road changed in said positional information changing step. - View Dependent Claims (22, 23, 24)
