Between 1915 and 1951, military topographical mapping in SA was conducted by Royal Australian Survey Corps (RASvy) units based outside the state. In February 1952, Army HQ Field Survey Section (Central Command Detachment) was established in Adelaide in a drill hall at Largs Bay. It was tasked with providing map coverage in the Woomera and Southern areas of the state. The section was subsequently reorganised as Central Command Field Survey Section moving firstly to Hampstead Barracks, Hampstead in 1953 and then into accommodation at Keswick Barracks in 1954. In 1957 the Section commenced mapping operations in the NT. The Unit was relocated to the old cavalry stables in 1961 and was redesignated Central Command Survey Unit and remained there till 1973. In 1970 the Unit was redesignated 4 Fd Svy Sqn and engaged in operations conducted in PNG from 1972 to 1974 inclusive. In 1973 the Squadron moved into a brand new two-storey specially designed and purpose built building adjacent to the old building. The old building then became the Squadron Q and Map store with an interconnecting lobby to the new building. Since 1975 the Unit was involved in the 1:50,000 Mapping Programme in WA, NT, QLD, SA and conducted many other operations within Australia and overseas. Post disbandment of the Corps the old Squadron building (cavalry stables) now houses the Army Museum of South Australia (AMOSA). The Royal Australian Survey Corps was amalgimated into the Royal Australian Engineer Corps in July 1996. In the lead up to this amalgamation, 4 Field Survey Squadron Keswick Barracks, Adelaide, South Australia was disbanded in 1995. A closing Ceremony was held on 25 November 1995 at 4 Fd Svy Sqn Keswick Barracks attended by about 208 former members of the Unit. A photo was taken of attendees at that event on the day and a list was prepared of attendees. All attendees were sent a copy of the photograph and the list of names as a momento of the Unit and the ceremony..1P A4 Print of an original photo of attendees at the 4 Fd Survey Sqn Closure Ceremony at Keswick Barracks 25 Nov 1995. .2P A4 Print of the names of the attendees at the 4 Fd Survey Sqn Closure Ceremony at Keswick Barracks 25 Nov 1995.

These informal and formal group photos were taken on the day of a CO’s Parade. Litho Squadron provided printing and photographic reproduction to the two DCP students. RA Svy also provided technical training to DCP students in map production skills such as, cartography and photogrammetry at the Army Survey Regiment and the School of Military Survey, Bonegilla. The Australian Defence Force over several years sponsored international students from counties such as Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands and Vanuatu.

All members of the Australian Survey Corps, that was later renamed the Royal Australian Survey Corps were expected to be proficient at freehand lettering and figuring. Initially all text on military maps was hand lettered in ink and an extremely high level of proficiency was required. Later technology changes meant that there was less reliance on hand lettering. This 17 x foolscap sized page booklet with light buff coloured cardboard covers held together with an ARNOS fastener was used to teach members of the Australian Survey Corps how to Hand Letter in 1947. Example practice lettering style work sheets are included at the rear of the document.17 x foolscap sized pages with light buff coloured cardboard covers held together with an ARNOS fastener.

This is a unique example of a hand drawn plane table sheet produced in the first year of the Australian Survey Corps by original members of the Corps. Roseblade and Lynch 5 Dec 1915. Of interest is the documented times that it took to create the original field sheet. Also of interest is the fact that this field sheet that was used to create the actual SYDNEY map sheet was contoured, many map sheets produced up until now were purely planimetric and lacked contouring that was needed for military use. This is a reproduction print of a photograph of the original field sheet and was printed at the Army Survey Regiment, Bendigo.Reprinted coloured Image of Australian Topographical Survey SYDNEY /56 III Southern Half, hand drawn NE Plane Table field sheet.

A Plane Table consists of a smooth wooden table surface (with metal strengthening supports) mounted on a sturdy base. The base, a three-legged Tripod, is designed to support the table over a specific point on land. The connection between the tabletop and the adjustable Tripod legs permits the user to level the table precisely, using bubble levels in a horizontal plane regardless of the roughness of the terrain. The Plane Table is a surveying device used in surveying and mapping to provide a level surface on which to make drawings, charts or maps. An alidade, with or without a telescope located on the tabletop is used to sight features and draw angles to that feature. Using these lines to the same feature from different setup locations it is possible to locate that feature on the map. Plane Tabeling was widely used by the early members of the Australian Survey Corps and in both World Wars. It remains a simple and effective tool to teach the fundamentals of mapping and surveying. It was simple to use and was reasonably robust and portable. See also item 6489.2 for the Plane Table Alidade.A wooden Plane Table with alloy fittings to strengthen and support the table top. The table is fixed to a three-legged wooden Tripod with cast alloy fittings and metal pointed tips.royal australian survey corps, rasvy, fortuna, army survey regiment, army svy regt, asr, 4 fd svy sqn, school of military survey

This is a set of six photographs of personnel from the Detachment - Army Survey Regiment taken in front of its main map production building at Bonegilla, Victoria in c1973. This cartographic map production sub-unit of the Army Survey Regiment operated in buildings owned by the School of Military Survey from 17th of June 1970 to the 30th of September 1985. A total of 800 topographic maps ranging in scale from 1:25,000 to 1: 250,000 scale were completed. A major focus of production in the 1970s was the cartographic completion of the Papua-New Guinea 1:100,000 map series and the Flexiflow quality control system was developed as a tool to coordinate production. The Flexiflow system comprised a series of job plans and charts linked to a task allocation to resource magnetic planning board. Using critical path analysis and task prioritisation, complex job planning was efficiently scheduled, and re-prioritisations readily made. Reproduction requirements were effectively coordinated by way of weekly courier to the Army Survey Regiment at Bendigo. Supervisors and technicians fully embraced the system as they could understand their role, others around them and the positive production achievements. WO1 Bill Boyd (who does not appear in this photograph) was the technical warrant officer for 11 years at the Detachment was awarded the OAM, the Order of Australia Medal for leading the development and the implementation of the Flexiflow system. By mid-1982, production of maps at these scales was undertaken digitally on Bendigo’s AUTOMAP 2 system and the Detachment reverted to production of small-scale large format RAAF aeronautical charts. Detachment personnel managed to produce 18 charts in the following two years, which was an impressive achievement for the staff, given major differences in format, specification and scales. Development of digital production of aeronautical charts in 1984-85 led to gradual reduction in production output and contracting out production was instigated to meet the shortfall and as a consequence the Detachment closed in September 1985.

This set of map prints was assembled as a training aid. The collection is a complete set of individual color prints of each colour used on the final printed maps for each map Joint Operations Graphic (JOG) JOG Ground and JOG Air versions. This map series was produced in two versions to help coordinate military Ground Operations and Air Operations. The ground users required that heights and measurements were in Metres, whilst air users required height information in Feet for altimeters. The Air Version also contained more Aeronautical information including safe flying height information called Maximum Elevation Figures (MEF). Later printing of JOG incorporated printing in just four colours Cyan, Magenta, Yellow and Black (CMYK).
