The Effects of Photo Characteristics Upon Location Determination in a Photogrammetric Facility. Final Report.
Sewell, E.; And Others
The operator of the Army Analytical Photogrammetric Positioning System (APPS) must perform a critical step in the coordinate determination procedure by the subjective comparison of dissimilar images. He must correlate reconnaissance mission imagery with aerotriangulated photographic stereoscopic pairs, known as data base imagery, and visually identify the image position on the data base of a target detected on the mission image. Results obtained from 40 image interpreters performing this task using vertical, oblique, and panoramic mission imagery are given. Two levels of target position difficulty were established: A-points located at terrain or man-made features mutually identifiable on both mission and data base imagery, and B-points remote from terrain or man-made features mutually identifiable on mission and data base imagery.
