Abstract : A method of analytical triangulation was evaluated and programmed for the IBM 709. This program with real photographic data as input, and weighting of input data, was used to perform an empirical test of the method. The test resulted in unrealistically small ground coordinate corrections. This is attributed to the assigned weights which overly constrained the solution. Further investigation as to the effect of parameter weighting on the adjustment and methods for inversion of large matrices are recommended. (Author)
