The salient features of a method of analytical triangulation operating directly on single photographs are described, and the close analogy with geodetic triangulation computation is demonstrated. Any combination of photographs, whether in stereo pairs, stereo triples, strips, sub‐blocks or blocks, is handled by forming the set of observation equations for each individual photograph in turn, and then taking all these sets together and solving them simultaneously by the method of least squares. Special procedures for dealing with very large numbers of variables are discussed, and certain applications of the method are indicated.
