This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory and North Queensland in 1959 – 1960. The surveyors were employed in the establishment of mapping and geodetic control. In this era surveyors used theodolites to observe horizontal and vertical angles and tellurometers to measure base line distances between survey stations. Laplace survey observations seen in Photo .1P was a series of precise observations carried out at geodetic survey stations to determine astronomic latitudes, longitudes and azimuths to achieve maximum precision in the survey network. Laplace observations were necessary in a geodetic network at every 6th survey station, however the National Mapping Council specified at this time the spacing would be ideally between 4-6 survey stations. The cairn shown in photo .4P was built by RASvy as a landmark over a trigonometric survey station. It was dismantled in 1960 to enable re-occupation and survey observations. It was not restored to the condition shown in the photo.This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory (NT) and Queensland (QLD) in 1959 – 1960.

This is a set of five photographs of CAPT James ‘Jim’ Leslie Stedman in the field demonstrating the setup of prisms used as electric distance measurement (EDM) receiver reflectors for tellurometer equipment and the sighting of a large surveyor’s light. This equipment was deployed in establishing mapping and geodetic control operations. The photos were most likely taken in the late 1950s or early 1960s. The tellurometers of this era were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. Jim Stedman later reached the rank of Colonel, was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983. Jim Stedman is demonstrating EDM equipment. See item 6180.16P, photos .14) to .16) for more information and photos of Jim Stedman’s EDM demonstration.

This is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954.

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.
