Abstract
A technique for enabling efficient surveying operation that uses a light-reflecting target is provided. A surveying apparatus is configured to survey a reflecting prism and includes a controller, a surface calculator, and a position calculator. The controller performs positioning on three or more points on the set-up surface on which the reflecting prism is set up, by using laser light. The surface calculator calculates a plane of the set-up surface based on the positioning data of the three or more points in a case in which the position of the reflecting prism is surrounded by the three or more points in terms of a horizontal plane. The position calculator calculates a point of intersection of the plane and a straight line from the position of the reflecting prism to the plane, as a position on the set-up surface, at which the reflecting prism is set up.
