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.

This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

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.

This pocket stereoscope was used to view a pair of separate and overlapping aerial photos as a single three-dimensional image. It was small and could be easily used in the field. Larger, mirror stereoscope were also available in some 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.

Aerial photos were used to make maps of forest types, timber resources, to survey logging areas and regeneration, to mark boundaries of public land and new plantations, to identify new roads and tracks, as well as for fire suppression. Infrared film was sometimes used to monitor insect and disease attack. The images needed to sharp, with high contrast, and in a large format (most were printed in B&W on 9-inch by 9-inch glossy photographic paper) with at least a 60% overlap to enable stereoscopic viewing and with a 20-30% side lap to allow for aircraft drift. Preferably, the photo scale was close to the final map scale avoid to problems when enlarging and to reduce distortion. Something was needed to supplement the very expensive and infrequent large-area photography programs. From the mid-1960s Victorian foresters began experimenting with small format 70mm and 35mm cameras which proved simple, practical, cheap and flexible. It was found that any SLR camera could be used provided it had a good quality lens and fast shutter speed (preferably down to 1/1000 second). Motorised cameras with a large film capacity had obvious advantages and were essential when access to the camera was not possible during flight. It is also essential for the shutter to operate at low temperatures and those lubricated with silicones were recommended. Components of a typical FCV Divisional Office system included – A Hasselblad or Vinten 70 mm format aerial camera with a focal plane shutter which could be electrically operated. Interchangeable lenses to allow for different photo scales and flying heights. Several large film magazines, which were loaded in a darkroom, each with a capacity of 100 feet or approximately 500 frames. A remote control for the camera in single-shot mode or automatic firing at selected intervals of 2 to 50 seconds. It also needed a frame counter. A light aircraft was modified with an internal mounting for the camera to keep it level and steady. Often a hole was cut through the floor for the lens. The aircraft also needed an inbuilt 12 Volt DC battery to operate the motorised camera shutter. The front passenger seat was generally removed to improve access to the camera. An Aldis drift sight was also fitted. This might be likened to an inverted periscope and is used to determine drift, to facilitate accurate navigation along flight lines and to determine the exposure interval for stereoscopic overlap.
