Australian Geodetic Survey and Geodesy
- From the mid 1820s until the adoption of electronic distance measuring in the 1950s, geodetic triangulation had been the main method of undertaking colonial, state, federal and defence surveys for Australian mapping. Implicit in any triangulation was the measurement of at least two baselines, unless only a couple of triangles were involved. One baseline near the start of the triangulation and the other near the end. Two baselines then provided an overall check on the accuracy of the completed triangulation. This work by Paul Wise gives an account of 63 triangulation baselines, plus a mention of a number of other baselines on islands and Tasmania. In doing so the history of geodetic triangulation surveys in Australia, is reviewed.
- The Division of National Mapping's part in the Geodetic Survey of Australia, Activities based on the Melbourne Office, 1951-1969, by RA (Reg) Ford.
In the New Year's day honours list of 1 January 1968 Reg was recognized with the award of the Medal of the Order of the British Empire - BEM (Civil)- for meritorious service to Australia's national mapping effort particularly to the national geodetic survey.
- The Geodetic Survey of Australia is one of the outstanding scientific achievements
of the post Second World War period. It was made possible by the foresight,
technical competence and physical effort of many government and private
surveyors and the use of modern precise theodolites, electromagnetic distance
measurement equipment, automatic levels, electronic computers and helicopters,
stated then Reader, Brian Thomas Murphy (1927-1983), of the University of Melbourne, Faculty of
Engineering, Department of Surveying, in 1973.
Mr Murphy went on to say that Klaus Leppert’s 1973 paper, Geodesy in Australia, 1956-72, discussed
implications of the actual surface of the earth, the geoid, and the spheroid;
it describes the Australian Geodetic Datum, the Australian Map Grid and the
Australian Height Datum; it outlines contemporary work on she definition of the
geoid in Australia and the application of satellite geodesy to the measurement
of two long base lines between Perth and Narrabri and between Thursday Island
and Narrabri for the worldwide Pageos Satellite Triangulation. Klaus Leppert’s
paper and Brian Murphy’s review are available via this link.
- Fifty years ago an insignificant rocky outcrop in the Northern Territory became the first calculated origin and centre of Australia. This location was then marked by a specially constructed rock cairn in which was set a bronze plaque indicating that this point was the Johnston Geodetic Station, also sometimes called the Johnston Origin. This article explains the importance of this point in Australia's survey and mapping history.
- On 21 April 1966, the National Mapping Council adopted the Australian Geodetic Datum 1966 (AGD66). This datum was later proclaimed in the Commonwealth Gazette No. 84 on 6 October 1966. AGD66 was the first Australian datum and now fifty years later preparations are well underway for the new 2020 datum. Whether we say Happy Birthday or RIP AGD66, its determination was a necessary and significant event in Australia's mapping history and its significance is briefly reviewed in this article Australian Geodetic Datum 1966 : Fifty Years On.
- The Geodetic Survey of Australia by Albert Francis Hurren in 1959, from Cartography 3:38-48.
- With the launch on 24 June 1966 of PAGEOS (Passive Geodetic Earth Orbiting Satellite), a global geodetic network was established to observe this satellite and establish a uniform geodetic datum. Commencing in 1967, Australia's contribution to the success of this project was not insignificant and can be viewed via this link.

Geodetic Observatory - Orroral
- National Mapping's Astro-Geodetic Observatory at Orroral, 1974-1998, details the history of the activities undertaken at or by the observatory and its staff. Included are Lunar Laser Ranging and later Satellite Laser Ranging, the National Time Service, initially at Mount Stromlo before being administratively moved to National Mapping on 27 September 1971 and physically to Orroral in 1974, and operation of the Photographic Zenith Tube (PZT) at Mount Stromlo from 1971 to 1985. The shell of the Observatory was subsequently Heritage Listed on 2 June 2016.

Mapping Control and Compilation (Photogrammetry)
- Australian mapping was largely based on photogrammetry where ground survey information was integrated with aerial photography to produce a contoured line map of selected scale. This selection of personal, historical material accumulated during the Natmap era covers photogrammetric, mapping and map printing topics as listed here.
Mugnier's 1972 paper Photogrammetric Instruments for the US Army (IRE Transactions on Military Electronics, No.64. pp.39-43) is here.
- Five hundred years on, Mercator's legacy in the Australian Map Grid (AMG), the basis for Australian topographic mapping, is recognised.
- The National Geodetic and Topographic Survey, by Bruce Phillip Lambert, presented at the Conference of the Institution of Engineers (Australia), Canberra, April 1956. This paper was given just before the National Mapping Office in the Department of the Interior was transferred to the Department of National Development on 2 July 1956 as the Division of National Mapping.

- One in a Million by William Sear former Chief Drafting Officer, National Mapping, 1964.

- This 1998 paper by David Roy Hocking titled NATMAP Early Days, Map Compilation from Aerial Photographs 1948-1970s (The Globe, No.47, pp.16-33) described the methods used to compile maps from aerial photographs by National Mapping from its earliest days to the 1980s; from aerial photo indexes, mosaics, radial line plots, to slotted template assemblies and shift & trace or Zeiss Sketchmaster to stereoplotting of map detail and contouring from stereoscopic models formed from overlapping aerial photos using Kern PG2 and Wild B8 instruments is covered.
- In 1965 the Commonwealth Government embarked on a programme of re-mapping continental Australia over a period of 10 years at a scale of 1:100,000. This program required an innovative approach which is described in this 1967 paper 'Control Surveys for 1:100,000 Mapping'. In 1969 this "brochure" article was published by the department.
- While map compilation was one of the main roles of the National Mapping Melbourne office, in this article Brian Murphy recalls that almost all of the 1: 100,000 scale map components of a 1: 250,000 sale map sheet in the region north of Albany, Western Australia, in Natmap's area of responsibility were compiled by the Canberra office.
- The Wild, model IV, B8 Stereomat was the first photogrammetric machine to automate much of the stereoplotting process. Along with Zeiss Jena's Topocart and Zeiss Oberkochen's SEG V rectifier, these instruments were the basis of National Mapping's orthophotomapping program. This article describes this program and contains papers on the development of the Stereomat.

- In the late 1960s Nat Map began storing some mapping data digitally. As processes variously known as Computer Aided Drawing, Computer Assisted Cartography, Automated Plotting, Automated Cartography and Automated Photogrammetry evolved the traditional manual map generation stages also evolved into the complete capture and storage of map data digitally. In 1987, the Hermannsburg (5450) 1: 100,000 scale map sheet, was the first sheet to be completely produced by digital methods in Nat Map, and also the last map required to complete its NTMS program. Described in this article The Division of National Mapping's Adoption of Digital Mapping Techniques is the path taken by Nat Map to fulfil the objective of digital mapping capture once and use many.

- Permanent Committee on Tides and Mean Sea Level
At its 37th Meeting in Perth during 18-20 September 1979, the National Mapping Council established a Permanent Committee on Tides and Mean Sea Level. Initially, the Committee consisted of a representative of the Flinders Institute for Atmospheric and Marine Sciences together with nominees of the Director of National Mapping and the Hydrographer, RAN as well as co-opted members from National Mapping Council member organisations and the Australian Association of Port and Marine Authorities.
The Committee's Circulars 1, 2 and 3 may be viewed via this link and a 1983 paper, by Gordon Homes, on the Committee's aims and activities is available here.
The Permanent Committee on Tides & Mean Sea Level (PCTMSL) is today a technical sub-committee of The Intergovernmental Committee on Surveying and Mapping (ICSM), with representation from national, state, port and scientific agencies engaged in the determination of tides and sea level.
