Analogue Aerial Triangulation

Analogue aerial triangulation procedures for application on the precision photogrammetric plotting machinery are dealt with in a simple way, and the mathematical basis of the procedures is given. Various ways of reconstructing individual spatial models formed by overlapping pairs of aerial photographs are examined, and ways of improving scale transfer between adjoining models are investigated. Consistency of fit at corresponding positions in the adjoining models also is considered. Results of a theoretical investigation into the accuracies of strip triangulations using some different orientation procedures indicate that some improvement is still possible in the lateral tilt determination and scale transfer between spatial models.
