This collection of 17 photographs of Air Survey Squadron aerotriangulation equipment and personnel was taken at the Army Survey Regiment, Fortuna, Bendigo, circa 1989. The PDP 11/70 minicomputer was the operating system introduced in 1977 as the mainframe system for the control of the APC4, aerial triangulation block adjustments, SORA OP Analytical Orthophoto control, APR Analytical Terrain Profile Recorder computation, graphics, and general computing. The OMI/Nistri AP/C-3 analytical plotter shown in photo .1P to .6P and .9P was introduced in 1972–1973. The Zeiss (Jena) Stecometer analytic stereocomparator for air photography shown in photo .16P 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. Wild PUG4 point transfer devices as shown in photo .17P, were introduced in c1968 superseding the PUG2 devices. PUG4 devices were used by technicians 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.

Although it’s unknown when these two photos were taken, the South African Pattern Mk IV Slotted Template Machine was in service from 1936 to 1952. The machine was used to cut slots and holes in an acetate film medium. This template was then used to fit several runs of aerial photography to ground control points at a desired scale with a substitution of the templates in the assembly. Radial slots on the templates from central holes representing the photograph’s principal point (centre) were placed over hollow metal studs mounted over control points on the scaled base sheet. The studs represented the intersection of radial lines through common points of detail of overlapping photos. A pricker was used to transfer from the photo-points to the templates. The slotted template methodology was later used as an essential aero-triangulation exercise in advance courses conducted at the School of Military Survey.These three photographs are of a slotted template machine used in aero-triangulation. The first two photographs were printed on photographic paper and are part of the Army Survey Regiment’s Collection. The photographs were scanned at 300 dpi. The third photograph was captured from a collection using a smart phone. .1) and .2) - Photo, black & white, 1936-1952.

These five photographs of map production and the car park area were taken at Fortuna, Bendigo, c1980s. The first three photographs were taken in Air Survey Squadron, where aerotriangulation and digital photogrammetric extraction of topographic features from aerial photography were undertaken. Photo .4P was taken in Cartographic Squadron’s Correcting Section, located in the Attic. The technicians were probably involved in a rapid response map production, as they all were wearing field uniforms. The Army Survey Regiment’s Duty Room, RAP and Carpark appear in Photo .5P.

These six photographs were taken at an Army Survey Regiment Open Day at Fortuna Villa, Bendigo on the 24th of February 1990. This occasion was one of several events held to commemorate the 75th anniversary of the formation of the Royal Australian Survey Corps. Although historical tours of Fortuna occurred on a regular basis, this was the first technical open day since 1972. The Royal Australian Survey Corps recognised that an Open Day was the best way for the local community in Bendigo to gain an insight into the unit’s important role as Defence’s map production agency, its technical equipment, and its economic importance to Bendigo. It also gave them an opportunity to tour through historic Fortuna Villa. This occasion is covered in more detail in page 143 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.
