MAP INFORMATION CREATING DEVICE, MAP INFORMATION CREATING METHOD, AND MAP INFORMATION CREATING PROGRAM

摘要

A three-dimensional road object (303a) has a road width (W), a thickness (H), and a length (L). The three-dimensional road object (303a) corresponds to a link (401). On the top of the three-dimensional road object (303a), a road surface texture (501) is repeatedly drawn. A map information creating device can extracts shape data (310) on the three-dimensional shape including the cross section (S) composed of the road width (W) and the thickness (H). The length (l) of the shape data (310) can be the length of one sheet (one period) of the road surface texture (501) in the length direction of the three-dimensional road object (303a). One sheet of the road surface texture (501) and drawing period information P(P=(L)/(l)) can be also extracted. Further, from the link (401), link length information (the length (L) of the link (401)) can be extracted.
