ADMAP is a Gridmerged compilation of over 700 individual survey TMI grids, with a cell size of approximately 80 m (in fact it is 0.00833333 degrees). An ERMapper vector file called "survey_boundaries.erv" contains the survey boundaries, and may be displayed on top of any images of these data. By using the information selection, individual survey boundaries selected can be identified by their grid name, which contains the four digit project number. The meta-data for the particular survey can then be viewed in a reference such as: http://www.ga.gov.au/image_cache/GA3715.pdf. It is particularly important when contemplating using the composite grid data to take into account the differing survey parameters, such as flight-line spacing and acquisition height, and how they may affect the precision and spectral content of the data from one area to another.

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>

The RADARSAT satellite was developed by the Canadian Space Agency (CSA) and was launched on 4 November 1995. It has a C-band, Synthetic Aperture Radar (SAR) sensor on board. The SAR is an active microwave sensor capable of imaging earth resource targets regardless of time of day, cloud, haze or smoke cover of an area. The instrument is classified "active" as it emits the energy necessary to image the earth's surface. In contrast, "passive" or "optical" sensors rely on the sun's reflected energy to image the earth. This sensor can operate in a variety of imaging modes to suit a range of applications. Depending on the beam mode, the SAR ground swath widith varies between 50 and 500 kilometres, and the pixel resolution varies between 10 and 100 metres. The sensor has HH polarisation. ACRES Radarsat archive consists of extensive coverage from August 1997 to late 1999. ACRES currently do not have an agreement with RSI but can acquire data if downlink is granted by RSI.

Geoscience Australia is distributing the Australian Geographic Reference Image (AGRI), a national mosaic which provides a spatially correct reference image at a 2.5 metre resolution across Australia. Geoscience Australia developed AGRI to address the need for a higher resolution reference image, of known accuracy, over the entire Australian continent. Geoscience Australia developed AGRI between July 2009 and June 2011. The project was made possible by a combination of new data from Japan's Advanced Land Observing Satellite (ALOS) which produced panchromatic observations at 2.5 metre resolution; new `full pass' processing techniques for rectification of satellite imagery developed in the Cooperative Research Centre for Spatial Information and included in the Barista software; Geoscience Australia's expertise in Geodesy and Global Positioning System, and the capabilities of the Australian Spatial industry in GIS database design, field survey and image processing. Pixel size: 2.5 metres for UTM Zone mosaic and 0.0001 deg (~10 m) for Australia continental mosaic. File format: Generic BIL files with ER Mapper and ENVI ASCII header for UTM Zone mosaic. ECW compressed files for both Zone mosaic and Continental mosaic.
