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.

This set of 30 photographs of the Army Survey Regiment’s Fortuna Villa and surrounding facilities was taken circa 1985. The photos feature much of Fortuna’s exterior and most of the out-buildings spread over the property’s fifteen acres of grounds. After Defence took possession of Fortuna in 1942, the Q-store and engineering workshops were added during the wartime period. Soldiers were accommodated in tents during WW2 for 20 years next to the parade ground before the construction of accommodation buildings in 1962. In 1990 most of the weatherboard buildings in the Q-store area were replaced. A climate-controlled building was also constructed to house a map library and digital data media. This photo set also includes the exterior of Air Survey Squadron’s Building 16 and two modular buildings -16A and 16B that were added in the early 1980s to accommodate map production and technical services. See item 6457.22P for photos of Fortuna Villa’s interior that were taken at the same time.This set of 30 photographs of the Army Survey Regiment’s Fortuna Villa and surrounding facilities was taken circa 1985.

This collection of 17 photos was most likely taken in c1978-1980. The AUTOMAP 1 computer assisted cartography and mapping system was introduced in 1975. The components of AUTOMAP 1 were the Input Sub-System of four Wild B8s stereoplotters and three Gradicon digitising tables, the Optical Line Following Sub-System – Gerber OLF, the Verification Sub-System – Gerber 1442 drum plotter, the General Purpose Sub-system – HP21MX computer and the Output Sub-System – Gerber 1232 flatbed plotter). The first map was published in 1978 (Strickland 3665-3, 1:50,000). AUTOMAP 1 was the first computer assisted cartography and mapping system utilised by the Survey Corps and was the first system used by Australian mapping organisations. The history of the AUTOMAP 1 system is covered in more detail with additional historic photographs, in pages 116-118 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4. See items 6122.20P, 6410.24P, 6183.19P, 6184.20P, and 6200.5P for additional photographs of the AUTOMAP 1 system.This is a set of 17 photographs of Air Survey Squadron military and civilian personnel operating AUTOMAP 1 equipment at the Army Survey Regiment at Fortuna, Bendigo, c1978-1980.
