摘要

A deformed map automatic generation system is described in which deformed map generating means ( 34 ) generates a deformed map from a positional relationship fixing map, in which display road areas are drawn with display target objects while fixing the positional relationships of the display road areas with the display target objects, by deforming a shape of one display road area drawn in the positional relationship fixing map while maintaining the positional relationships. Deformed map outputting means ( 36 ) output the deformed map generated by the deformed map generating means. Accordingly, a deformed map for an arbitrary area can be automatically generated.
