The principal object of this paper is to present a direct mathematical method of finding the elevation of the exposure station and consequently the tilt and the swing, if desired, of an aerial photograph. Since three points in space determine a plane (Fig. 1), the three vertical distances Za, Zb, and zc. (Fig. 2), from a horizontal plane through the exposure station to the images, a, b, and c on the photograph of the three ground control points, A, B, and C, determine the position of the photograph in space. Therefore, the swing of the photograph is not necessarily required provided the values of za, Zb, and zc. have been specified. Furthermore, in the solution of the space resection problem only relative quantities are required expressive of the three ground points.
