(Ms) Berres Hoddle Colville is a local Surrey Hills resident and is a descendant of Robert Hoddle. Robert Hoddle was the first Surveyor General of Victoria. He arrived in Australia in 1823 and was one of the very earliest surveyors to explore, measure and map large areas of this vast, varied and difficult countryside, in a burgeoning era of pastoral settlement. 1837 saw him appointed Surveyor in Charge of the Port Phillip District. This book is based firmly on substantial extracts from Hoddle's own diary and other writings. Includes black and white sketches, maps and colour pages.Robert Hoddle was the first Surveyor General of Victoria.

Compass, divider, and caliper are basically instruments that have two legs pivoted to each other at the top and are concerned with small-distance measurement or transfer. The compass and divider have straight legs; the caliper has curved legs. Dividers and Calipers were known to both the Greeks and Romans, though the caliper was uncommon. A divider with a circular sector, or wing, connecting the two legs was sketched in 1245, its modern counterpart is the wing divider with a thumbscrew clamp and screw for fine adjustment. Or the marine dividers used to measure the distance a vessel has travelled by transferring the vessels distance from a map with the divider and transferring that measurement to a marine ruler to mathematical calculate the distance.Item is believed to be a replica/ copy of a 19th century map calipers used in marine navigation to determine distance travelled. Item was probably purchased between 1972-1975 to add to the marine displays at Flagstaff Hill.Stainless steel dividers used in navigation charts. Top half is alloy plated.

This is a set of eight photographs of technicians operating photogrammetric equipment in Air Survey Squadron, Army Survey Regiment, Fortuna, Bendigo. c1960s to c1980s. The Wild A9 Stereocomparator and Wild B9 stereo plotter were introduced in 1962. The Wild B8 stereo plotter was introduced in 1966. Technicians used the Wild A9 Stereocomparator to accurately measure between pass, tie, and survey control points on aerial photographs. The Wild B9 and B8s were used for plotting topographic detail and contours. These analogue machines were manually controlled by adjusting the control knobs for the orientation of the 3D image. The B9s used a four and a half square, and the B8s used a nine-inch square photo image on a film or glass diapositive which allowed highly accurate extraction of map features. At first, plotting with B8 and B9 stereo plotters was undertaken at the aerial photography scale of 1:80,000 in pencil onto a controlled plotting sheet. Sheets were then inked up and reduced photographically to the 1: 100,000 publication scale for scribe impression production. In the early days topographic detail and contours were plotted with a pencil or ink pen mounted at the far end of the pantograph arm. The plotting procedure was upgraded to direct plotting in ink with photographic reduction to publication scale. In 1975 four B8s were upgraded with tri-axis locaters as part of the Input Sub-system to enable digital extraction to AUTOMAP 1’s topographic database. When AUTOMAP 2 was introduced in 1982 these B8s were upgraded, and additional machines added to expand the Army Survey Regiment’s digital capture capability.

This is a set of seven photographs of map grid production using co-ordinatorgraphs at the Army Survey Regiment, Fortuna Bendigo. c1960s to 1970s. The Aristo Co-ordinatorgraph introduced in 1962 was a large heavy steel framed light table with a scribing head that moved in a XY direction using a vernier calibrated measuring scale to 0.001 of an inch. Whilst hand operated it was much quicker and accurate than manual grid and graticule calculation, plotting and scribing. Mapping PNG presented the Regiment with many challenges. WO1 Farrington and CPL John Dean developed computer software for the digitally controlled co-ordinatorgraph, the Calcomp 718 Flatbed Plotter. Much time was saved by automatically plotted cartographic grids and graticules, and automatically draw base compilation sheets complete with aerial triangulated stereo model control. This could be used for a number of maps and was the first step towards map automation. The history of co-ordinatorgraphs is covered in more detail with additional historic photographs, in pages 50 to 51 and page 88 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4. SGT Bill Boyd appearing in photo .1P reach the rank of WO1 and for 11 years was the technical warrant officer at the Detachment Army Survey Regiment located at Bonegilla, Victoria. He was awarded the OAM, the Order of Australia Medal for the development of the Flexiflow quality control system. This system comprised a series of job plans and charts linked to a task allocation to resource magnetic planning board. Using critical path analysis and task prioritisation, complex job planning was efficiently scheduled, and re-prioritisations readily made. Reproduction requirements were effectively coordinated by way of weekly courier to the Army Survey Regiment. Supervisors and technicians fully embraced the system as they could understand their role, others around them and the positive production achievements. Bendigo.

This is a set of 10 photographs of Cartographic Squadron technicians undertaking map production tasks in at the Army Survey Regiment, Fortuna, Bendigo circa 1968 to 1975. Production was undertaken on the top floor of Fortuna Villa. The Fotosetter type setting machine shown in photos .1P and .2P. replaced the letterpress method of type production in 1956. CPL Arty Lane specialised in the operation of the Fotosetter type setting machine for many years. For more information on the Fotosetter, see page 71 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4. The computer based Editwriter Model 7500 typesetting system shown in photos .3P and .4P. was introduced in 1975 as a replacement to the aging Fotosetter. It was operated by a specialised technician, who generated a large variety of map type styles and sizes quickly and reliably, as well as text panels. Output on Copy proof adhesive backed stripping type film replaced messy wax and spray adhesives in 1978. The Editwriter capability supported all RASvy units and its contractor type setting requirements. The Aristo Co-ordinatorgraph shown in photos .5P to .7P was introduced in 1962. It was a large heavy steel framed light table with a scribing head that moved in a XY direction using a vernier calibrated measuring scale to 0.001 of an inch. Whilst hand operated it was much quicker and accurate than manual grid and graticule calculation, plotting and scribing.

The scribing process as shown in photos .8P to .9P was the cartographic process of drafting features such as drainage, relief, vegetation, roads and culture on specially coated map reproduction material. The cartographic technician scribed out the map feature such as a contour to a specified line width on the map sheet, using a tool affixed with a sapphire tipped cutter. The quality control edit (Proving) stage of map production shown in photo .10P was the first opportunity to independently and systematically inspect a proof of the map.This is a set of 10 photographs of cartographic Squadron technicians undertaking map production tasks at the Army Survey Regiment, Fortuna, Bendigo, c1968 to c1975.

A surveyor was employed to measure the land designated as Yangery, County of Villiers, in the Borough of Warrnambool. The area on the map is similar to the earlier Farnham Survey undertaken by William Rutledge in the 1850's. Warrnambool was a Borough between 1863-1883. Coutours, waterways, sea and other significant points are shown. The distances are accurately measured. This survey map was used for planning future land sales, recreation areas and roads. WILLIAM RUTLEDGE (1806-1876) William Rutledge surveyed the land known as Farnham in southwest Victoria in 1843. His tenants made him a profitable business from working the land there. In 1863 Rutledge moved from nearby Port Fairy to Farnham and became very successful in breeding sheep, which he imported from J.R. Kirkham of Lincolnshire, England. He also bred horses on his land. The survey map of Yangery is important for its connection with renowned surveyor William Rutledge. The map shows the growth of landholders in the district when compared to the original Rutledge survey of the 1850's.Survey map of Yangery, titled "Yangery - County of Villiers".
