Abstract: A major factor limiting photogrammetric accuracy is the effect of residual errors that displace the photographic image from its ideal (projective) position. Sources of image error and their typical magnitude are reviewed in the context of the photogrammetric accuracy requirements in: (1)Map compilation; (2)aerotriangulation to supply supplementary control for map compilation; and (3)aerotriangulation to provide higher order control for geodetic, engineering, and cadastral survey tasks. The basis for image error tolerances of 18 μm (0.71 mil), 6 μm (0.24 mil), and 3 μm (0.12 mil), respectively, are presented for these photogrammetric processes.
