The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

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.

Aspects of the tectonic history of Palaeo- to Mesoproterozoic Australia are recorded by metasedimentary basins in the Mt Isa, Etheridge, and Coen Provinces in northern Australia and in the Curnamona Province of southern Australia. These deformed and metamorphosed basins of Palaeo- to Mesoproterozoic Australia are interpreted to have been deposited in a tectonically-linked basin system based on similarities in depositional ages and stratigraphy (Giles at al 2002). Neodymium isotope compositions, when combined with U-Pb geochronology, are independent data that are important tools for inferring tectonic setting, palaeogeography and sediment provenance in deformed and metamorphosed terrains.

Geoscience Australia`s involvement in Papua New Guinea mapping includes managing the production of maps for select urban areas as part of a MOU between Department of Defence and PNG. In addition, Geoscience Australia distributes some (now aging) 1:100,000 scale maps produced by the Department of Defence for much of Papua New Guinea. 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.
