Three-dimensional map data generating system, three-dimensional map data generating method and three-dimensional map data generating program

A three-dimensional map data creation system for creating three-dimensional map data including an external shape and a height of each of structures, comprising:

• a unit for acquiring said external shape from already acquired two-dimensional map data, and obtaining said height using a photograph in which the structures described in said two-dimensional map data are imaged, wherein said photograph is taken from a high-altitude part or a rooftop of a structure having a height larger than an average height of said structures, and a structure near a base station antenna in a wireless communication system providing a wireless communication service or a structure visible from said base station antenna is imaged in said photograph.
