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. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models 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. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He 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.

This sextant is very similar to a 1915 Sextant design. A sextant is an astronomical instrument used in measuring angular distances especially the altitudes of sun, moon and starts at sea determining latitude and longitude.This sextant is an example of a 19th-century marine instrument used for finding location at sea. It was made by London scientific instrument maker Troughton and Simms, which originated in 1826 and continued until 1922.Sextant and its fitted square wooden box. The handle of the sextant is carved with a cross-hatched pattern.

Before metrication was introduced into Australia in the 1970s land was measured in chains and links. Many old parish plans show length measurements in chains and links. Area was shown in acres, roods and perches. Gunter's chain was used for measuring distance in surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). Gunter developed the measuring chain of 100 links. The chain and the link, became statutory measures in England and subsequently the British Empire. After metrication units of length were measured in meters and area in hectares. The chain was later superseded by steel ribbon tape.The 66-foot long (1 chain) Gunter's Chain was a fundamental instrument for land surveying. It is divided into 100 links (each 7.92 inches long) which are marked off into groups of 10 by brass tags with 'fingers' to indicate 10, 20, 30, 40 and 50 links from the hand grips, thus simplifying intermediate measurements. Each end of the chain is fitted with a brass hand grip. It was heavy and sturdy enough to be dragged through the bush and over rough terrain on surveying transects. Giving rise to the common forestry term "chainman" for the person tasked with dragging it. 1 chain = 100 links = 22 yards = 66 feet = 792 inches = 4 rods, poles or perches. 10 chains = 1 furlong 80 chains = 1 mile 1 acre = 10 square chains = 4 roods = 160 square rods, poles or perches.forest measurement, surveying, forests commission victoria (fcv)
