Horizontal positional accuracy assessment of historical ARGON satellite photography
A sophisticated photogrammetric adjustment technique was investigated to derive accurate positional information from the digitized declassified historical satellite imagery. We used extended Gauss-Markov model to adjust observation equations for differential rectification. Results show that we can obtain about 150 m horizontal accuracy of orthorectified ARGON image, which corresponds to the horizontal resolution of the image. The result is very promising concerning very wide of coverage (540 km×540 km) of single frame film ARGON imagery whose size is 120mm×120 mm. We identified that the consideration of Earth curvature effect for input photo coordinates is essential for the accurate orthorectification using the very wide ground coverage film. Result also suggests that the usefulness of declassified historical satellite imagery for scientific studies of very wide area when they are employed a sophisticated photogrammetric technique such as differential rectification.
