The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. This instrument was used as a training aid to help teach surveyors at the Royal Australian Survey Corps School of Military Survey.

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.

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.

Before metric measurement was introduced land was measured in chains and links. The chain was a precision part of a surveyor's equipment. It required frequent calibration, yet needed to be sturdy enough to be dragged through rough terrain for years. A standard survey chain is 66 feet (or 20.117m) long and made up of 100 links. Each link is 7.92 inches (approximately 201mm) long, measured from the inside of the loop. The handles are for tensioning the chain in use, they are not part of the length of the chain. In pre-metric units, there were 80 chains to 1 mile (equals 1.609km) This surveyor’s chain has an 8-inch link pitch, with markers at 10 link intervals. This metal surveyor’s chain (or Gunter's Chain) has an 8-inch link pitch, with markers at 10 link intervals, and handles at either end. A Surveyor’s Chain was 66 feet long, and made up of 100 links connected by two rings. A link in measurement includes the two rings at each end. gunter's chain, survey chain, surveyor s chain, perch, rood, surveying

The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.

This is a superbly crafted cartographic mapping instrument. It is housed in its own high-quality purpose-built oak box. Made in the Netherlands from 1950 onwards. This instrument is from c 1956. it is a very high-quality military grade stereoscope that was generally used by photographic interpreters such as intelligence analysts but was equally useful for mapping activities. The stereoscope was used to examine 3D aerial photographic images. This instrument has a particularly useful capability to scan over the 3D stereo model using X and Y movement knobs, rather than having to physically move the aerial photographs. In the public and private sector it was also useful for photogrammetric interpretation for Forestry and Agricultural purposes.
