In 1966, all geodetic surveys in Australia and New Guinea were recomputed and adjusted on the new Australian Geodetic Datum (AGD). There was now a homogenous system of coordinates (other than heights) for geodetic survey stations all over Australia, free from discontinuities caused by changes in origin.A A4 blue card covered manual containing 84 Pages of text and diagrams and Graphic Annexes A-J.

These draft Specifications set out the Standards for the production of topographic maps within the Commonwealth of Australia at scales of 1:50000 and 1:25000 and are designed to satisfy the basic requirements of both civil and military map users.Hard cover, cloth, Red, 11 Annexes, Supplementary documents.royal australian survey corps, rasvy, fortuna, army survey regiment, asr

Australia is governed by a Federal Government and by six State Governments. National coordination of their respective geodetic survey and topographic mapping activities is effected on the advice of a National Mapping Council. Twenty years ago, at least 95% of Australia was poorly mapped and what maps existed were in need of revision. only a small area of the continent was covered by horizontal geodetic control and there was no scheme for a national levelling survey. Over the intervening period there has been an urgent and increasing demand for topographic maps varying from large scale contoured maps in support of specific engineering projects to rapid reconnaissance maps required for mineral prospecting in remote areas. Superimposed on this has been a defence requirement, specifically for military training areas, and generally for maps of the whole country. During the period much progress has been made. This paper reports on the progress from early colonial days through to the present time and finally hazards a prediction of future trends.Photocopy of 18-page typed report including diagrams, stapled top left-hand corner.

This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory and North Queensland in 1959 – 1960. The surveyors were employed in the establishment of mapping and geodetic control. In this era surveyors used theodolites to observe horizontal and vertical angles and tellurometers to measure base line distances between survey stations. Laplace survey observations seen in Photo .1P was a series of precise observations carried out at geodetic survey stations to determine astronomic latitudes, longitudes and azimuths to achieve maximum precision in the survey network. Laplace observations were necessary in a geodetic network at every 6th survey station, however the National Mapping Council specified at this time the spacing would be ideally between 4-6 survey stations. The cairn shown in photo .4P was built by RASvy as a landmark over a trigonometric survey station. It was dismantled in 1960 to enable re-occupation and survey observations. It was not restored to the condition shown in the photo.This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory (NT) and Queensland (QLD) in 1959 – 1960. The photographs were printed on photographic paper and are part of the Army Survey Regiment’s Collection. The photographs were scanned at 300 dpi. .1) - Photo, colour, 1959.
