HUN Historical Landsat Images Mine Foot Prints v01

## **Abstract** 

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.



The near-real-time data dissemination service is delivered by Earth Observation from Space - a Program of Geoscience Australia responsible for acquiring, curating and analysing remotely sensed data from satellites orbiting the earth.



Landsat 7 and Landsat 8 data is scene based and comprises preview images in JPG format (one at high and one at low resolution) and individual files per spectral band in TIFF format. Included with the data are licence and product descriptions where applicable.



All files are in folders sorted according to date of acquisition and are made available within 3 to 6 hours of the receipt of source information.



Only the last few days of data is held on the server due to the size of the imagery files. Downloading data requires an FTP enabled browser.

Landsat ETM+, TM and MSS data is available under Creative Commons Licence 3.0

## **Dataset History** 

Geoscience Australia receives and processes data from the Landsat series of satellites. The Landsat Program is the longest running satellite series for imaging Earth from space. The first satellite in the series was launched in 1972, and since then seven satellites have been launched. The eighth satellite, the Landsat Data Continuity Mission, is due to be launched early 2013. The Landsat Program has produced one of the most successful satellite ventures in space history with Landsat 5. Commencing in March 1984, the satellite had an expected life of 3 years. As of 2012 Geoscience Australia no longer processes or distributes Multispectral Scanner (MSS) data.



Of the sensors carried, the Multispectral Scanner (MSS) with 80-metre pixels and four spectral bands was found to provide information of unforeseen value. In July 1982, the launch of Landsat 4 saw the inclusion of the Thematic Mapper (TM) sensor with a 30-metre resolution and 7 spectral bands. Both sensors are on Landsat 5.



The newest in this series of remote sensing satellites is Landsat 7. Launched on 15 April 1999, Landsat 7 has the new Enhanced Thematic Mapper Plus (ETM+) sensor. This sensor has the same 7 spectral bands as its predecessor, TM, but has an added panchromatic band with 15-metre resolution and a higher resolution thermal band of 60 metres. The ETM+ sensor also has a five percent absolute radiometric calibration.



Landsat MSS data was recorded over Australia by USGS from 1972 to 1979. Geoscience Australia (then ACRES) began acquisition of this data in September 1979. Acquisition of Landsat MSS image data ceased in December 1997. From late 1979 we have archived nearly every pass over Australia and continue to receive and archive data from Landsat 7 daily.
