The cartographic collection of the Doc Fisher Geoscience Library consists of the maps and air photos created or acquired by agency staff since the formation of BMR in 1946. This includes maps produced by agencies which have merged with these over the years, such as AUSLIG. Maps held include: Australian geological map series (1:250,000, 1:100,000 and the 1 mile series); topographic maps produced by NATMAP and its predecessors (1:250,000, 1:100,000 and 1:50,000) - latest editions only; various Australian geochemical, geophysical and other thematic maps; geoscience map series from other countries acquired on an exchange basis, including some with accompanying explanatory notes; Non-series maps acquired by donation or exchange; atlases. The Air photos are predominantly those used for mapping Australia and, to a lesser extent, Papua New Guinea and Antarctica, by BMR/AGSO from the 1940s to the 1980s. Geographical coverage of the sets is not complete, but many individual photos are unique in that they have pin points, overlays or other markings made by teams in the field. The Papua New Guinea photographs in the collection may, in many cases, be the only existing copies. Flight diagrams are also held for many (but not all) sets of air photos. Some other related materials, such as montages of aerial photographs (orthophotos), are also represented in the collection.

This map is part of the AUSTopo - Australian Digital Topographic Map Series. It covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 516 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and at least 110 kilometres from north to south. The topographic map shows approximate coverage of the sheets. The map may contain information from surrounding map sheets to maximise utilisation of available space on the map sheet. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries.

Although the positional accuracy of spatial data has long been of fundamental importance in GIS, it is still largely unknown for linear features. As early as 1987 the US National Center for Geographic Information and Analysis identified accuracy as one of the key elements of successful GIS implementation. Yet two decades later, while there is a large body of geodetic literature addressing the positional accuracy of point features, there is little research addressing the positional accuracy of linear features, and still no accepted accuracy model for linear features. This research aims to address some of these shortcomings by exploring the effect on linear feature positional accuracy of feature type, complexity, segment length, vertex proximity and 'scale'. A geographically sensible error model for linear features using point matching from a test line to a reference line of higher accuracy is developed and a case study undertaken using well-regarded and commonly used Australian topographic datasets. Half a million points are matched between test and reference lines for a range of topographic feature types at a spectrum of 'scales' and summary statistics are generated that shed light on the relationships between positional accuracy and 'scale', feature type, complexity, segment length, and vertex proximity. It is found that (a) metadata for the tested datasets significantly underestimates the positional accuracy of the data; (b) positional accuracy varies with 'scale' but not, as might be expected, in a linear fashion; (c) positional accuracy varies with feature type, but not as the rules of generalisation suggest; (d) complex features lose accuracy faster than less complex features as 'scale' is reduced; (e) the more complex a real-world feature, the worse its positional accuracy when mapped; and (f) accuracy mid-segment is poorer than accuracy end-segment.

Australian Diamond Deposits as of November 2006

Surface geology of Australia 1:1,000,000 scale, South Australia The 1:1 million-scale "Geology of South Australia" dataset has been compiled from the latest published 1:250 000-scale and some 1:100 000-scale geological maps, modified to incorporate results of recent research by PIRSA in the Olary Domain. Much of South Australia is covered by Cenozoic regolith, mainly sand plains, dunes, playas and colluvium, with lesser silcrete, calcrete and laterite. Six main Precambrian provinces have been recognised: the Gawler and Curnamona Cratons, Musgrave Block, Officer Basin, Adelaide Fold Belt (Geosyncline) and Coompana Block (concealed). The Gawler Craton outcrops in the centre and south. Neoarchaean igneous and sedimentary rocks of the Mulgathing and Sleaford Complexes form the basement of the Craton and were metamorphosed to granulite facies during the period 2.7 to 2.4 Ga. Clastic and chemical sediments of the Hutchison Group were deposited along the eastern margin of the Craton during the Palaeoproterozoic, and were subsequently deformed during the Kimban Orogeny (1850 to 1700 Ma). Little deformed Mesoproterozoic sediments and the Gawler Range Volcanics were deposited unconformably over the older rocks, mainly in the east of the Craton. Coeval granites of the Hiltaba Suite are distributed throughout the Craton. Three domains of the Curnamona Craton - the Olary Domain, and Mt Babbage and Mt Painter Inliers - outcrop in the central east. They consist of Palaeoproterozoic schist and gneiss, metamorphosed and disrupted during the Olarian Orogeny (1700-1580Ma), and intruded by Palaeo- to Mesoproterozoic granite. The inliers were further disrupted by the Delamerian Orogeny (~500Ma) and are surrounded by Neoproterozoic to Cenozoic sediments. The Musgrave Block in the northwest of the State comprises quartzofeldspathic orthogneiss and granite, and minor pelitic, siliceous and calcareous metasediments. Widespread metamorphism at about 1600 Ma was followed by extensive granite intrusion at about 1500 Ma. Emplacement of the mafic-ultramafic Giles Complex at about 1080 Ma occurred towards the end of metamorphism and granite emplacement of the Musgravian Orogeny (1225-1075 Ma). During the Petermann Orogeny (~540 Ma), granulite of the southern Musgrave Block overthrust amphibolite facies gneiss north of the Woodroffe Thrust. Tectonic disruption on regional scale shear zones continued to the end of the Alice Springs Orogeny (400-350 Ma). During Neoproterozoic to Cambrian times, sedimentation occurred in shelf and trough settings in the Officer Basin (south of the Musgrave Block), and in the Adelaide Fold Belt. At times these basins were linked, yielding similar sedimentary sequences. The Adelaide Fold Belt was folded and disrupted during the Delamerian Orogeny (~500 Ma) and locally intruded by granite. Many of the intrusions are concealed by Murray Basin sediments, but coeval granites are exposed in the Padthaway Ridge inboard of the southeast coast. Small Precambrian inliers are exposed elsewhere in the state. They include: the Ammaroodinna and Yoolperlunna Inliers southeast of the Musgrave Block; Peake, Denison and Mount Woods inliers north of the Gawler Craton; and Houghton, Warren, Aldgate, Oakbank, and Myponga Inliers within the Adelaide Fold Belt. Carboniferous to Permian glaciation affected much of the state, and was followed by deposition of mixed marine and terrestrial sediments in the Mesozoic Eromanga Basin and Cenozoic Eyre, Murray, and Eucla Basins.

This work was undertaken to extend regional mapping in the central and western portions of the A.C.T. and to provide a geological map of the Cotter River Area for use in engineering investigations. The regional geology portion of the Cotter Valley between Gingera and Bull's Head had previously been mapped on a scale of 1/2 mile to the inch, and this map was extended, by the recent survey, northwards to the Territory border and north-easterly to the Murrumbidgee River.
