Abstract : The feasibility of using triplets of photographs for analytic aerotriangulation as opposed to the conventional stereopair is investigated. A procedure consisting of: (1) triplet relative orientation, (2) triplet assembly, and (3) transformation and adjustment to ground control has been developed, programmed in FORTRAN, and used on an electronic computer. Equations for triplet relative orientation and least squares adjustment are included. Tests were performed with three types of data: (1) theoretically accurate fictitious data; (2) fictitious data in which a random distribution of errors was applied to plate coordinates; and (3) actual photographic data. Results from test cases using each of the three classifications of data indicate considerable improvement over aerotriangulation with stereopairs.
