Geoscience Australia is distributing Landsat MSS, TM and ETM+ data for 19 epochs or time frames ranging from 1972 to 2010 covering Australia. This data has been provided by the Department of Climate Change and Energy Efficiency formerly known as the Australian Greenhouse Office (AGO). This data is only available through Geoscience Australia and not through the Department of Climate Change and Energy Efficiency.

Processing Ortho-corrected, radiometrically corrected and mosaiced into tiles. All data is calibrated to a common geographic and spectral base (AGO year 2000 base). Note: Single scene boundaries can be quite obvious within a tile due mainly to the seasonal changes associated with different acquisition dates. Tiling system Tiles approximate 1:1 million map sheets covering Australia. Most tiles contain overlap beyond the quoted extents. Coverage View a detailed map of the 1972 to 2005 epoch extents. Download an ESRI shapefile of the date and boundary (datebound) of each Landsat scene used to produce the epochs from 1972 to 2005. The introduction of SLC-Off and bumper mode Landsat products for the 2006 epoch has meant that a new method has been required for creating datebound information. The new 2006 date bounds are currently in raster form as opposed to the traditional vector. The rasters are in ER Mapper Storage format (ERS) format as Geodetic or MGA projections - file size 61 or 66 Gb. Pixel size 25 metres TM and ETM+ and 50 metres MSS.

Current understanding of Australia's geothermal resources is based on limited data such as temperature measurements taken in petroleum and mineral boreholes across the country. Heat flow studies are rarer, with existing publicly available compilations containing less than 150 heat flow data-points for Australia. Both temperature and heat flow data are unevenly distributed and, where no data exist, the available information has been interpolated over large areas to generate national-scale maps. Geoscience Australia has acquired the field and laboratory equipment required to measure heat flow. It began thermal logging of boreholes across Australia in late 2008 and has since collected 155 temperature logs. In late 2009, the thermal conductivity meter became operational, allowing the project to begin thermal conductivity measurements of samples collected from logged boreholes. To help clear some of the backlog of samples collected during 2008-09, the measurement of some of these samples has been contracted out. This record details the first set of new heat flow interpretations to be released by Geoscience Australia. The remaining temperature logs will be interpreted for heat flow and released, as thermal conductivity data for these holes become available.

Australia magnetic anomaly pixel map

The data set provides outlines for the maximum extent of Australian geological provinces and their components, including sedimentary, igneous and metallogenic provinces, both onshore and offshore. These data were compiled as part of Geoscience Australia's integrated digital information system to provide improved accessibility and knowledge relating to the petroleum and minerals geology and prospectivity, and to provide a national stratigraphic and tectonic framework for Australia. The current dataset is not complete for Australia, and covers only offshore sedimentary provinces and a selection of sedimentary, igneous and metallogenic provinces in onshore Australia.

The first edition ACE - Australian Continental Elements dataset is a GIS representation of the lithosphere fabrics of the Australian plate, interpreted from linear features and associated discontinuities in the gravity anomaly map of continental Australia (Bacchin et al., 2008; Nakamura et al., 2011) and the global marine gravity dataset compiled from satellite altimetry (Sandwell & Smith, 2009). It should be used in context with these input data sources, at scales no more detailed than the nominal scale of 1:5 000 000.

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.
