In 1990 MAJ Bob Williams was the OC of Technical Development Cell. He won first prize for his entry ‘Innovations in Cartographic Communication’ in the individual category at the 2nd Australian Institute of Cartographers and BHP Engineering Technology Research and Development Awards. The award was announced at the 1990 Australian Cartographic Conference in Darwin where MAJ Williams presented his entry. At the time he had completed PhD studies at the Australian Defence Academy and was the first Survey Corps officer to complete studies at this advanced level. Also, in 1990 the Royal Australian Survey Corps’ meritorious achievements were formally recognised by the Senate of the Australian Parliament in a Notice of Motion on 31st of May 1990. The Royal Australian Survey Corps also featured in the issue of a commemorative stamped envelope issued by Australia Post.

This is a set of 12 photographs of A Section, 1st Topographic Survey Troop taken from the 25th of May to the 12th of June 1966 during their deployment to Vung Tau, Vietnam. Led by OC CAPT Bob Skitch, the ten personnel from A Section 1st Topo Svy Tp and six personnel from supporting units were the first contingent from the Royal Australian Survey Corps deployed to provide topographic support to the Australian Task Force in Vietnam. They arrived in Saigon, Vietnam on the 10th of June 1966 enroute to the Australian Reinforcement Unit (ARU) “back beach” camp in Vung Tau. The ten RA Svy technical personnel from 1st Topo Svy Tp deployed were: WO2 David Christie, SGT Stan Campbell, SGT Dave King, CPL Jim Roberts, CPL Dennis Duquemin, CPL Des Ceruti, SPR Derek Chambers, SPR Brian Firns, SPR Joe O’Connor and SPR Ron Smith. External personnel deployed were: WO2 Snow Rollston from Northern Command Field Survey Unit, T/CPL Peter Clarke – orderly room corporal, T/CPL Alan Carew – Technical Storeman, SPR Stan Johns – Map Storeman, SPR Boots Campbell – batman/driver and PTE BNF Brunning – cook. The ship featured in photos .1P and .2P was the aircraft carrier HMAS Sydney on its 4th voyage to Vietnam. On board were SGT Stan Campbell and SPR Brian Firns, tasked to manage A Section’s stores and equipment. The rest of A Section deployed to Vietnam by air on the chartered Qantas 707B ‘City of Longreach'. A Section’s main tasks were to establish a Theatre Grid, map compilation and map revision; Engineer Survey Support in the camp and to the civil community; give assistance to the Cordon Search Missions by producing large scale plots from aerial photos with every house and fence etc plotted; and then reproduce these by silk screening usually, within a 24-hour period. RA Svy’s support concluded with the withdrawal of Australian troops from Vietnam in 1972. More information on the A Section, 1st Topographic Survey Troop and the Army Survey Regiment’s supporting role is provided in pages 89 to 94 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.This is a set of 12 photographs of A Section, 1st Topographic Survey Troop (1st Topo Svy Tp), taken from the 25th of May to the 12th of June 1966 during their deployment to Vung Tau, Vietnam.

Multiplex mechanical stereoplotting equipment was used at the Army Survey Regiment, Fortuna Bendigo. c1950s. Multiplex equipment was imported from the UK in 1951 and introduced in the following year, to accelerate map production output covering CMF training areas at 1:25,000 map scale. Multiplex plotting was a productive advancement replacing the ‘Arundel’ method of graphical plotting planimetric detail that was expensive and slow, especially in timbered mountainous terrain. Air photos were made into small diapositives and mounted on racks in the exact position relative to when the aerial photos were taken. The technicians operated the Multiplex in a darkened room, with one photo projected with a green filter and the other through a red filter to form a 3D view of the overlapping photos. The 3D model projected onto a platen, which was a small platform that was raised up and down. The technician viewed the 3D image with special glasses fitted with red and green lenses. In the centre of the platen was a small pinhole that served as a floating mark, with a vertical pencil located exactly below the pinhole. This tracing table was moved to follow the topographic feature or contour line and draw it on the paper underneath. The technician raising or lowering the platform’s floating mark to match the height of the 3D terrain. It also replaced the slotted template method of mechanical adjustment of strips of aerial photography, however was restricted to each strip rather than between strips in the block. Although the Multiplex was phased out of production in 1968, it was used in the training of photogrammetry and aero-triangulation at the School of Military Survey located at Bonegilla, Victoria until the early 1990s. The history of the Multiplex is covered in more detail with additional historic photographs, in pages 50 to 51 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.
