A transfer unit generates a transferred image by transferring a whole or part of a determination target closed curve, which represents an outline of an airspace and is formed of one or more line segments on a spherical surface, from its original position to another position on the spherical surface in such a manner that the transferred image has no intersection point with the determination target closed curve. A line segment generation unit generates, from the line segments forming the determination target closed curve, a determination line segment an intersection point with the transferred image and having no intersection point with other line segments forming the determination target closed curve. An airspace recognition unit recognizes, as the airspace, a region in which the determination line segment is not present, the region being one of two regions on the spherical surface that are defined by the determination target closed curve.
