Abstract
The gridding of unrectified space photographs is described from two viewpoints. The first considers a mathematical model relating points on the surface of the earth to their image on a space photograph. An adjustment procedure is then derived for near vertical photographs. This procedure would allow for the determination of the location and orientation of the space photograph if ground control and approximate values of the parameters are available. The second viewpoint considers that, for many space photographs, we do not know to a sufficient accuracy the location and orientation parameters of the photograph. We then perform a least squares surface fit of the ground control to the coordinates on the photograph. Either viewpoint yields equations that may be used to place grids on the space photographs. Future work is suggested.
