  • The Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. The Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. The Multispectral Scanner (MSS) sensor has been the primary Earth-observing instrument. MSS images in four spectral bands (called Bands 4-7 on LS1,2&3 and 1-4 on LS 4&5) covering the visible and near infrared regions of the electromagnetic spectrum. The MSS ground swath is 185 kilometres wide, with a nominal 80 metre pixel resolution. The archive of ACRES MSS data dates from 1979 onwards. ACRES MSS archive contains data from the following Landsat satellites: Landsat 2 commenced November 1979, ceased Feb 1982 Landsat 3 commenced November 1979 ceased August 1982 Landsat 4 commenced August 1982, ceased May 1984 Landsat 5 commenced 9 April 1984, ceased November 1997 - Band 4 (original band 7) data poor quality from 29 April 1994 - Band 4 (original band 7)switched off permanently 20 August 1995 Note that MSS data from Landsat 3 & 4 is of poor quality and requirements for this data need to be discussed with ACRES prior to purchase.

  • These images are clipped to represent the 1:100 000 map sheet they fall within as per the topographic series. For example, the image im2855.bil covers the same area as the Marble Bar (2855) topographic map. There are 51 individual sheets in total. The data was clipped from the larger mosaic of original Landsat scenes processed using: Directed Principal Components/Band Ratio Image: RGB pc2[4/3 : 5/7] : 5/4 : 1+ 7 Expressing relationships between: hydrosilicates/clay/carbonate: iron oxide : quartz

  • GA through the Unlocking the Landsat Archive (ULA) Project is funded by the Department of Industry, Innovation, Science, Research and Tertiary Education (DIISRTE) to process and make available well calibrated Landsat imagery for the period 2000-2010. Having now processed this data to produce well calibrated optical surface reflectance data products at the National-Scale we are now able to promote these products through various means. This promotional animation shows the time-series "stacked" mosaics for each month of the year.
