  • These datasets are a subset of the mosaic of Australian Landsat MSS images of Australia. ldsatmss.bil is a 500m pixel Lambert Conformal Conic projected dataset. ldsatmssdd.bil is a 0.0048 degree geographic projected dataset. NOTE The original image is located in the corporate storage system at /d/geo/store/data/image/landsat_mss/aus_mosaic. In this directory there is extensive documentation (OVERVIEW.TXT) which describes all contents.

  • The dataset provides the spatially continuous data of the seabed gravel content (sediment fraction >2000 µm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.01 decimal degree resolution raster format. The dataset covers the Australian continental EEZ, including seabed surrounding Tasmania. It does not include areas surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands or Australia's marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. This dataset supersedes previous predictions of sediment gravel content for the Australian Margin with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant regions. This dataset is intended for use at national and regional scales. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

  • Due to licence restrictions on the National Electricity Transmission Substations dataset, the metadata statement is the only information available for release. For further information contact clientservices@ga.gov.au The dataset held by GA contains the spatial locations for Electricity Transmission Substations in Australia in point format as a representation of the substation features.

  • Due to licence restrictions on the National Electricity Transmission Lines dataset, the metadata statement is the only information available for release. For further information contact clientservices@ga.gov.au This dataset contains the high voltage electricity transmission lines that make up the electricity transmission network in Australia .

  • Geoscience Australia is releasing its 2013 version of the Marine Seismic Surveys Shape files and Kml files. These files have been updated to include recent openfile surveys. The spatial files have been created from a cleansed, updated collection of p190 navigation files. This navigation collection has grown from the checking of navigation submitted to the GA Repository under Offshore Petroleum and Greenhouse Gas Storage Regulations, checking of the 2003 SNIP navigation files and the digitisation of old survey track maps as required. Soon the individual p190 files will be available for download through the new NOPIMS delivery system. The collection is based on P190 navigation files which follows the UKOOA standard. Extensive industry standard metadata associated with a seismic survey is preserved in the attribute tables of these datasets. The files have been categorised into 2D and 3D seismic files. A further category contains legacy data that still requires checking. The process of adding to this navigation database and checking of legacy data is ongoing. Geoscience Australia (email - AusGeodata@ga.gov.au) appreciates being notified of any errors found in the navigation collection. The data is available in both KML and Shape file formats. The KML file can be viewed using a range of applications including Google Earth, NASA WorldWind, ESRI ArcGIS Explorer, Adobe PhotoShop, AutoCAD3D or any other earth browser (geobrowser) that accepts KML formatted data. Alternatively the Shape files can be downloaded and viewed using any application that supports shape files. Disclaimer: Geoscience Australia gives no warranty regarding the data downloads provided herein nor the data's accuracy, completeness, currency or suitability for any particular purpose. Geoscience Australia disclaims all other liability for all loss, damages, expense and costs incurred by any person as a result of relying on the information in the data downloads.
