Historical information
This collection of five photos was most likely taken in 1980. Wild PUG4 point transfer devices were used by technicians in Air Survey Squadron to stereoscopically view the photography containing the survey control points and the mapping aerial photography. The Control points were transferred from the control photography to the mapping diapositives of aerial photography by drilling their locations into the photographic emulsion. The Zeiss (Jena) Stecometer analytic stereocomparator for air photography was introduced at Air Survey Squadron in 1963. Aerotriangulation production was expedited using computers for analytical photogrammetric processes. The technician accurately measured between pass, tie, and survey control points on aerial photographs.
