This service provides Australian surface hydrology, including natural and man-made features such as water courses (including directional flow paths), lakes, dams and other water bodies. The information was derived from the Surface Hydrology database, with a nominal scale of 1:250,000. The National Basins and Catchments are a national topographic representation of drainage areas across the landscape. Each basin is made up of a number of catchments depending on the features of the landscape. This service shows the relationship between catchments and basins. The service contains layer scale dependencies.

These pages comprise the National Geoscience Datasets Internet Facility which delivers AGSO clients online access to AGSO's National scale spatial geoscience information. AGSO has responsibility for the production and online access to primary geoscience information of relevance to resource issues for industry, government and the general public, provided in the form of digital datasets that cover the Australian continent and/or Australian marine jurisdictional areas. This facility will provide efficient, modern digital-era access to all the geoscience information available in current maps and associated digital databases at the best possible resolution. To add to this as new geoscience datasets are released they will become available on the National Geoscience Datasets download page and be viewable within the National datasets online GIS web mapping tool.

Contains a medium scale vector representation of the topography of Australia. The data include the following themes: Hydrography - drainage networks including watercourses, lakes, wetlands, bores and offshore features; Infrastructure - constructed features to support road, rail and air transportation as well as built-up areas, localities and homesteads. Utilities, pipelines, fences and powerlines are also included; Relief - features depicting the terrain of the earth including 50 metre contours, spot heights, sand dunes, craters and cliffs; Vegetation - depicting forested areas, orchards, mangroves, pine plantations and rainforests; and Reserved Areas - areas reserved for special purposes including nature conservation reserves, aboriginal reserves, prohibited areas and water supply reserves.

A structural transect along a ridge entering Wheeny Gap from the west provides important insight into the nature of faults comprising the Lapstone Structural Complex (LSC). Sheared sandstone outcropping along the ridge east of the Kurrajong fault scarp suggests that the Kurrajong Fault is a steeply east-dipping reverse-fault, in accordance with the interpretation of seismic profiles further to the south. A previously unrecognised west-dipping reverse fault (Wheeny Gap Fault) with at least several tens of metres of displacement was observed in a cliff face on the northern side of Wheeny Gap, several hundred metres east of the Kurrajong Fault. Relatively recent activity is suggested on the Wheeny Gap Fault as it laterally displaces the cliff face formed during the passage of a knickpoint relating to initial relief generation across the Lapstone Monocline up Wheeny Creek. Earthquake hypocentres recorded over the last several decades occur predominantly at depth to the west, and have been used to suggest the presence of a blind west-dipping reverse fault, into which the Kurrajong and Wheeny Gap faults must link at depth. We present an evolutionary model for the LSC based upon this architecture which reconciles evidence for late Cenozoic uplift across the LSC and the observation that the Rickabys Creek Gravels overlie shale on the Cumberland Plain and sandstone on the Lapstone Monocline. This model suggests that the findings of a major seismic hazard assessment of the Sydney Basin, which concludes that magnitude MW7.0 and greater earthquake events might be expected on the LSC on average every 15-30 ka, should be treated with caution. This expectation of regular recurrence must be tempered by the possibility that a large part of the relief relating to the complex might have formed in the late Miocene or earlier, and the evidence from other Australian intraplate faults suggesting that large earthquake occurrence is markedly temporally clustered.

This service has been created specifically for display in the National Map and the symbology displayed may not suit other mapping applications. Information included within the service includes the linear locations for surface hydrology, including natural and man-made features such as water courses (including directional flow paths), lakes, dams and other water bodies and marine themes. The data is sourced from Geoscience Australia 250K Topographic data and Surface Hydrology data. The service contains layer scale dependencies.

The Australian Topographic map service is seamless national dataset coverage for the whole of Australia. The map portrays detailed graphic representation of features that appear on the Earth's surface. These features include cultural, hydrography and relief themes. SS, MS and LS refer to Small, Medium and Large Scale datasets.
