Product Specifications Coverage: Partial coverage, predominantly in northern Australia, along major transport routes, and other selected areas. About 1000 maps have been published to date. Currency: Ranges from 1968 to 2006. Coordinates: Geographical and UTM. Datum: AGD66, new edition WGS84; AHD. Projection: Universal Transverse Mercator UTM. Medium: Paper, flat copies only.

At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours, localities and some administrative boundaries. Product Specifications Coverage: Australia is covered by more than 3000 x 1:100 000 scale maps, of which 1600 have been published as printed maps. Unpublished maps are available as compilations. Currency: Ranges from 1961 to 2009. Average 1997. Coordinates: Geographical and either AMG or MGA coordinates. Datum: AGD66, GDA94; AHD Projection: Universal Transverse Mercator UTM. Medium: Printed maps: Paper, flat and folded copies. Compilations: Paper or film, flat copies only.

The Eastern Highlands form a broad arch, with similar cross sections along its length, and varying altitude of its axis. At least on the western margin in Queensland and near Sydney, most of the uplift was by warping. Mesozoic sediments preserved on the summit and flanks of the highlands prove that most of the uplift was after the Early Cretaceous in Queensland, after the mid Triassic near Sydney, and after the Triassic in Tasmania. Uplift of the highlands was most likely initiated at the time of change of the sedimentation pattern and tectonics, 95 Ma ago, as suggested by Jones and Veevers, except that uplift is thought to have started in the Jurassic in Tasmania. Denudation rates vary with local relief. The Cainozoic average rate for Queensland and New South Wales is near 3 m.Ma-1, and for Victoria and Tasmania 5-7 m.Ma-1. Gravity studies show that the Eastern Highlands are on relatively weak lithosphere, so the denudation would have resulted in denudation isostatic rebound of the local area, and the total amount of tectonic uplift is given approximately by the smoothed altitude of the present highlands. In general, the amount of denudation is smaller than the total amount of tectonic uplift. The timing of the tectonic uplift is not well determined, but most is earlier than mid Cainozoic, and there is evidence that possibly one third of it was during the late Cainozoic. The early tectonic uplift is thought to be due to removal of the lower lithosphere from beneath the highlands at the time of rifting to form the Tasman and Coral Seas, leading to uplift both by crustal underplating, and by the short and long-term effects of crustal heating. Later tectonic uplift is thought to be caused by crustal underplating associated with Cainozoic basaltic volcanism.
