Abstract
A surveying device includes: an angle-of-view value acquisition unit which acquires the angle of view of a telescope; and a manipulation amount correction unit which, on the basis of the angle of view acquired by the angle-of-view value acquisition unit, corrects the displacement amount of the telescope such that the displacement amount of the telescope with respect to the rotation amounts of a horizontal tangent screw and a vertical tangent screw when the angle of view of the telescope is a first angle of view is smaller than the displacement amount of the telescope with respect to the rotation amounts of the horizontal tangent screw and the vertical tangent screw when the angle of view of the telescope is a second angle of view wider than the first angle of view.
