This stereoscope was used to view a pair of separate and overlapping aerial photos as a single three-dimensional image. Smaller units and could be easily used in the field but this larger, mirror stereoscope was used in offices. The aerial images were used to map forest types, timber stands, new roads and tracks, firebreaks, boundaries of timber harvesting, plantations, bushfires, insect and disease attack and so on In 1928, the Forests Commission undertook its first major aerial photography project over 15,000 acres of forest which is said to be the first of its kind in Australia. During the Second World War, large areas of Victoria were photographed by RAAF and used to produce orthophoto maps. By 1945 aerial photography of 13,000 square miles (3.4 M ha) was completed, including much of the inaccessible eastern forests. The Forests Commission started developing its own small format photography in the early 1970s. Simple, cheap and rapid methods of obtaining photographs using 70mm and 35mm cameras were developedFoldable metal stereoscope in wooden box with mirror covers Ex Dept of Defenceforests commission victoria (fcv), surveying, forest measurement

This collection of 14 photos was most likely taken in the 1970s and 1980s in Air Survey Squadron. The PDP 11/70 minicomputer shown in photo .1P was the operating system introduced in 1977 as the mainframe system for the control of the APC4, aerial triangulation block adjustments, SORA OP Analytical Orthophoto control, APR Analytical Terrain Profile Recorder computation, graphics, and general computing. Technicians used the Wild A9 Stereocomparator shown in photo .2P to accurately measure between pass, tie, and survey control points on aerial photographs. The Zeiss D2 Planimat Stereoplotter shown in photos .3P to .4P was used for analytical orthophoto control. It was introduced in 1972-1973 The Zeiss (Jena) Stecometer analytic stereocomparator for air photography shown in photos .5P to .11P and .14P was introduced at Air Survey Squadron in 1963. Aerotriangulation production was expedited using computers for analytical photogrammetric processes. The technician accurately measured between pass, tie, and survey control points on aerial photographs. Wild PUG4 point transfer devices shown in photos .12P to .13P were introduced in c1968 superseding the PUG2 devices. PUG4 devices were used by technicians to stereoscopically view the photography containing the survey control points and the mapping aerial photography. The Control points were transferred from the control photography to the mapping diapositives of aerial photography by drilling their locations into the photographic emulsion.This is a set of 14 photographs of Air Survey Squadron personnel operating aerotriangulation equipment at the Army Survey Regiment at Fortuna, Bendigo, c1970s to 1980s. Photographs .1P to .13P were on 35mm colour slide film and scanned at 96 dpi. Photograph.14P was printed on photographic paper and was scanned at 300 dpi.

The Aerial Drip Torch (ADT) was an idea conceived in Canada in the 1970s by John Muraro It was developed in 1982 by the New Zealand Forest Service to become the Ashley Aphid Helitorch. Forestry Tasmania acquired one of the machines and modified it in February 1987. Also known as a dragon helitorch it consisted of a large 135-litre tank containing jellied petrol, a displacement pump, propane ignition system, burner nozzle and fire extinguisher system. It was first trialled in Victoria at Swifts Creek in 1991 and the Aerial Drip Torch (ADT) has now become standard practice.Two Aerial Drip Torches (ADTs) were built in the 1990s by the Fire Equipment Development Centre at North Altona, They were developed in conjunction with the Department of Conservation and Land Management in Western Australia. The first was trialled during the 1991/92 autumn burning season. The machine proved to be successful and a second machine was introduced in 1998 to assist with burning operations across the State. The ADTs were commonly used for regeneration burning (controlled burning of logging slash). The first ADT introduced in 1992 had a dry weight of 160kg and a capacity of 130 litres, providing about an hour of operation. Following initial use, systematic modifications were adapted including improved ignition of gel at the drop tube, installation of an air bleed valve at the pump to assist pump priming and improved mounting brackets for the CO2 bottles and propane canister attached to the machine. The second, and lightweight ADT, introduced in 1998 had a dry weight of 68kg and a capacity of 200 litres due to a smaller lightweight frame and plastic (Polyfin) tank. In operation the ADT is suspended below a helicopter via four strops attached to the vessel and a cable to the helicopter cargo hook. Gelled fuel is dispensed via a drop tube which is attached to the pump outlet of the machine, and ignited via a gas torch. Safety features built into the first ADT were: a brass melting plug designed to be activated at 200 C bursting disc designed to burst at170 Kpa should the vessel over pressurise. a pressure relief valve set to 35 Kpa ( vessel operated between 16 &34 Kpa) a low pressure sensor designed to shut down the machine should the vessel pressure drop below 15Kpa. the vessel is filled with CO2 above the gelled fuel to eliminate ignition with in the vessel. CO2 is used to expel any residue of ignited gel from the drop tube to prevent ignition when flying outside the boundaries of the burning area.

Multiplex mechanical stereoplotting equipment was used at the Army Survey Regiment, Fortuna Bendigo. c1950s. Multiplex equipment was imported from the UK in 1951 and introduced in the following year, to accelerate map production output covering CMF training areas at 1:25,000 map scale. Multiplex plotting was a productive advancement replacing the ‘Arundel’ method of graphical plotting planimetric detail that was expensive and slow, especially in timbered mountainous terrain. Air photos were made into small diapositives and mounted on racks in the exact position relative to when the aerial photos were taken. The technicians operated the Multiplex in a darkened room, with one photo projected with a green filter and the other through a red filter to form a 3D view of the overlapping photos. The 3D model projected onto a platen, which was a small platform that was raised up and down. The technician viewed the 3D image with special glasses fitted with red and green lenses. In the centre of the platen was a small pinhole that served as a floating mark, with a vertical pencil located exactly below the pinhole. This tracing table was moved to follow the topographic feature or contour line and draw it on the paper underneath. The technician raising or lowering the platform’s floating mark to match the height of the 3D terrain. It also replaced the slotted template method of mechanical adjustment of strips of aerial photography, however was restricted to each strip rather than between strips in the block. Although the Multiplex was phased out of production in 1968, it was used in the training of photogrammetry and aero-triangulation at the School of Military Survey located at Bonegilla, Victoria until the early 1990s. The history of the Multiplex is covered in more detail with additional historic photographs, in pages 50 to 51 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.
