Landsat Mosaic

Geoscience Australia is distributing Landsat MSS, TM and ETM+ data for 19 epochs or timeframes ranging from 1972 to 2010 covering Australia. This data has been provided bythe 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.Epoch formatsEpochs are available as 1:1M tiles or as a Continental mosaic in the following formats:TilesEpoch Projection Bands File Format All MGA94 All bands except Band 6 (thermal) ERS/BIL 2004, 2005 & 2006 Geographic All bands except Band 6 (thermal) ERS/BIL Pre 2004 Geographic Bands 543 for TM & ETM+ and all bands for MSS ERS/BIL 2002 MGA94 Panchromatic only ERS/BIL 2002 Geographic Panchromatic only ERS/BIL Continental mosaicsEpoch Projection Bands File Format All Geographic 543/RGB bands for TM, ETM+ and MSS ECW 2002 Panchromatic Sharpened Geographic Bands 543 plus Panchromatic band ECW File sizes and mediaFile sizes of the data are significantEpoch Minimum Date Maximum Date Tile data - ERS/BIL Continental mosaic - ECW Total size Gb - MGA Total size Gb - Geographic Total size Gb - Geographic 2006 4/11/2005 7/10/2006 162.1* 145.0* 4.6 2005 5/12/2004 9/10/2005 96.1 85.3 4.2 2004 1/09/2003 25/09/2004 96.1 85.3 4.6 2002 (No Pan) 9/11/2001 27/11/2002 96.1 43.4 4.6 2002 Pan 9/11/2001 27/11/2002 64.1 57.8 N/A 2002 Pan sharpened 9/11/2001 27/11/2002 N/A N/A 4.6 2000 (No Pan) 14/07/1999 21/09/2000 96.1 43.4 4.6 1998 20/05/1997 31/08/1998 96.1 43.4 3.9 1995 11/06/1994 29/08/1995 96.1 43.4 3.9 1992 1/01/1992 11/03/1993 96.1 43.4 3.9 1991 27/09/1990 9/07/1991 96.1 43.4 3.9 1989 1/07/1989 3/04/1990 112.1 43.4 4.0 1988 12/07/1987 7/09/1988 16.1 14.5 3.7 1985 18/06/1984 20/07/1985 16.1 14.5 3.6 1980 21/09/1979 24/01/1981 16.1 14.5 3.7 1977 25/02/1975 20/12/1978 16.1 14.5 2.7 1972 28/07/1972 29/10/1976 16.1 14.5 3.5 *Includes date and boundary (datebound) data.Sensor/Epoch Landsat TM and ETM+ SLC-Off: 2006;Landsat MSS: 1972, 1977, 1980, 1985, 1988;Landsat TM: 1989*, 1991, 1992, 1995, 1998, 2004 and 2005; andLandsat ETM+: 2000 and 2002.*Includes simulated MSS from Landsat TM (MGA projection only). Projection Either MGA94 OR Geographic. Bands All bands except thermal bands - MGA coordinates; All bands except thermal bands - Geographical coordinates, 2004, 2005 & 2006 epochs;5,4,3 for TM & ETM+ and all bands for MSS - Geographical coordinates, Pre 2004 epochs only;Panchromatic band available separately only for 2002 epoch - MGA & Geographical coordinates. 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.
