Samenvatting
A major problem faced by personnel responsible for manipulating aerotriangulation data through transformation and adjustment programs in an electronic computer is that of isolating and detecting errors. This research produced an automated data analysis and rejection program to reduce the turn around time from initial entry to certification of the final adjustment. Parameters for establishing the smallest detectable errors for rejection were determined by analyses of error sources in ground control surveys, aerial photography, and aerotriangulation theory and operations. Some seldom considered theoretical and practical error sources in ground control surveys are discussed and resolved.
