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.

These data are a digital representation of information depicted on the printed maps of Seigal, Hedleys Creek, Carrara Range Region, Lawn Hill Region, Riversleigh, Constance Range Region, Mount Oxide Region, Mammoth Mines Region, Myally, Alsace, Coolullah, Kennedy Gap, Prospector, Quamby, Mount Isa, Mary Kathleen, Marraba, Cloncurry, Oban, Duchess Region, Malbon, Kuridala Region, Selwyn Region, Dajarra and Ardmore 1:100 000 Geological Series and Mount Drummond 1:250 000 Geological Series produced by AGSO, the Geological Survey of Queensland (GSQ) and Northern Territory Geological Survey (NTGS). Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, era, period and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA). The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests.

Outcrop geology was obtained directly from the following 1:250 000 map sheets: Marble Bar, Nullagine, Port Hedland and Yarrie. This dataset consists of both raster and vector data. Raster data which is unsigned 8 bit integer, can be viewed in Arc/Info, ArcView, MapInfo, ERMapper, ERViewer and ArcExplorer. Raster data which is 4 byte real data, can only be viewed and manipulated with an image processing package such as ERMapper.

This data package is an archive of geospatially located and other digital geological and geophysical data covering the Tennant Inlier in the Northern Territory, a portion of the North Australia Project undertaken to understand elements within the North Australia Craton and its boundaries. It includes digital geospatial data and/or images for a number of regional scale, 1:250 000 scale and 1:100 000 scale geological map sheets, mineral locations, geophysical images, company drill hole and rock chip locations, company and Geoscience Australia geochemistry, and other regional themes. It also includes geophysical gravity data acquired by the project in the Tennant Inlier, including an ERMapper data set.

These data are a digital representation of information depicted on printed maps from the Australia 1:250 000 Geological Series produced by AGSO and the Northern Territory Geological Survey (NTGS) between 1963 and 1998. The data are in a tiled format and are not seamless, although basic edgematching has been done where possible. Tiles are arranged according to the standard Australian 1:250 000 sheet breakup. The complete dataset is comprised of the 90 tiles covering the Northern Territory.
