ACRES acquired SPOT 2 satellite images over the Namoi River, between the towns of Walgett and Wee Waa in December 1997 and November 2000. The November 2000 image consists of 12 scenes in which floodwaters, peaking at 8 metres, inundating the region are visible as green and light blue. Extensive flooding is evident. The December 1997 image shows the area of the Namoi River without floodwaters. The Namoi River catchment area is more than 350 kilometres long and stretches from Walcha in the east to Walgett in the west. Other river systems in the region include the Gwydir, Castlereagh, Hunter, Macquarie, Macleay, Manning, Culgoa and Condamine. You can find these rivers on Geoscience Australia's interactive Map of Australia.

All 1:250,000 scale NATMAP topographic maps available on CD in ECW format as a seamless map image. Map projection is Equirectangular/Geographic/Geodetic/Plate Caree - best suited for measuring position and for use in conjunction with GPS. 1:1,000,000 scale maps and 50m Landsat satellite image are also included.

The Perth study is part of Infoterra's Global Seeps programme - a multi-phase two year exploration programme to create the definitive offshore seeps database for the worldwide exploration industry. The North Perth Basin study contains interesting indications of active petroleum systems. The study results support the renewed interest in the Perth Basin as a result of the recent exploration success at Cliff Head-1.

This CCT format specification follows the format coding conventions defined in the document " SAR DATA PRODUCTS FORMAT STANDARD Rev 2.0 10 March 1989 by CEOS SAR Data Standards Subgroup ". To improve compatibility between different installations, certain conventions have been used for the specification of the data formats on the CCT.

This ALOS processed data covers the area from Newcastle down to Batemen's Bay on the east coast of New South Wales for Geoscience Australia. The data has been delivered in a number of both tile and mosaic files. The data delivered to Geoscience Australia consists of 8 AVNIR scenes and 13 triplet PRISM scenes.

Regolith materials spatially and chemically associated with various types of ore deposits, such as iron oxides, manganese oxides and gold deposits for example, have the potential to be mapped and characterised using remote sensing techniques. With the release of new state-scale multispectral data such as the Advanced Spaceborne Thermal Emission and Reflectance Radiometer (ASTER) Geoscience map of Western Australia (Figure 1), these applications may be tested and evaluated, along with identifying ore deposit types and characteristics best suited to using remote sensing techniques. A world-first continental scale ASTER mosaic and pre-competitive geoscience products for Australia are planned for public release in August 2012. The ASTER products are designed to provide broad scale mineral group information for mineral explorers at the continental to prospect scale. The product will be particularly useful for obtaining information on remote or difficult to access areas of Australia. ASTER data consists of 14 bands from Visible and Near Infrared (VNIR) light, through Short Wave Infrared (SWIR) and Thermal Infrared (TIR) encompassing different reflectance and emission spectras from the top few microns of material on the Earth's surface (Figure 2).

Unlocking the Landsat Archive (ULA) project poster presentation outlining the background to the project, it's objectives and major components.

Geoscience Australia, ACRES distribute Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data for a series of epochs or time frames covering Australia. The first epoch is 1972. These data have been produced and provided by the Australian Greenhouse Office (AGO). AGO use the data in their National Carbon Accounting System for monitoring land clearing and revegetation. This data is only available through ACRES and ACRES Landsat Distributors, and not through the AGO. More information is available at <a href="http://www.ga.gov.au/acres/prod_ser/agosuite.jsp">http://www.ga.gov.au/acres/prod_ser/agosuite.jsp</a> This data is available in 1:1M tiles or as a full continental Mosaic. Tiles areas are available at: <a href="http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp">http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp</a>

Australia has been receiving Earth Observations from Space (EOS) for over 50 years. Meteorological imagery dates from 1960 and Earth observation imagery from 1979. Australia has developed world-class scientific, environmental and emergency management EOS applications. However, in the top fifty economies of the world, Australia is one of only three nations which does not have a space program. The satellites on which Australia depends are supplied by other countries which is a potential problem due to Australia having limited control over data continuity and data access. The National Remote Sensing Technical Reference Group (NRSTRG) was established by Geoscience Australia as an advisory panel in 2004. It represents a cross-section of the remote sensing community and is made up of representatives from government, universities and private companies. Through the NRSTRG these parties provide Geoscience Australia with advice on technical and policy matters related to remote sensing. In February 2009 the NRSTRG met for a day specifically to discuss Australia's reliance on EOS, with a view to informing the development of space policy. This report is the outcome of that meeting. Australia has some 92 programs dependent on EOS data. These programs are concerned with environmental issues, natural resource management, water, agriculture, meteorology, forestry, emergency management, border security, mapping and planning. Approximately half these programs have a high dependency on EOS data. While these programs are quite diverse there is considerable overlap in the technology and data. Of Australia's EOS dependent programs 71 (77%) are valued between $100,000 and $10 million and 82 (89%) of all these programs have a medium or high dependency on EOS data demonstrating Australia's dependency on space based imaging. Earth observation dependencies within currently active Federal and state government programs are calculated to be worth just over $949 million, calculated by weighting the level of dependency on EOS for each program. This includes two programs greater than $100 million in scale and one program greater than a billion dollars in scale. This document is intended as a summary of Australia's current space and Earth observation dependencies, compiled by the NRSTRG, to be presented to the Federal Government's Space Policy Unit, a section of the Department of Innovation, Industry, Science and Research, as an aid to space policy formation.
