Landsat Surface Reflectance
The United States Geological Survey's (USGS) Landsat satellite program has been capturing images of the Australian continent for more than thirty years. DEA takes the hundreds of thousands of images, prepares them for Australian conditions, and makes adjustments to correct inconsistencies caused by changes in the atmosphere each time an image is captured (i.e. absence or presence of cloud cover), so that the data can be analysed to provide information about our changing continent.
This corrected data set is known as Landsat Surface Reflectance, and it forms the basis for many of the other information products produced by DEA. Products derived from the surface reflectance collection include Fractional Cover, Water Observations from Space, the Intertidal Extents Model, and High and Low Tide Composites.
