Geoscience Australia Landsat and Sentinel-2 Analysis Ready Data Collection 3 This product takes Sentinel-2 and Landsat imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. Where Sentinel-2 and Landsat data are both available, the higher resolution Sentinel-2 data is used. This product combines: * Sentinel-2A https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-sentinel-2a-msi/ * Sentinel-2B https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-sentinel-2b-msi/ * Landsat-5 https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-landsat-5-tm/ * Landsat-7 https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-landsat-7-etm/ * Landsat-8 https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-landsat-8-oli-tirs/ * Landsat-9 https://docs.dea.ga.gov.au/data/product/dea-surface-reflectance-landsat-9-oli-tirs/ For service status information, see https://status.dea.ga.gov.au

Geoscience Australia Sentinel-2 Analysis Ready Data Collection 3 This product takes Sentinel-2A and Sentinel-2B imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. The imagery is captured using the Multispectral Instrument (MSI) sensor aboard Sentinel-2A and Sentinel-2B. This product is a single, cohesive Analysis Ready Data (ARD) package, which allows the analysis of surface reflectance data as is, without the need to apply additional corrections. The resolution is a 10/20/60 m grid based on the ESA Level 1C archive.

DEA Geometric Median and Median Absolute Deviation (Landsat 8 OLI-TIRS) This product provides statistical tools to exploit the time series of Earth Observation data available in Digital Earth Australia, providing annual images of general conditions and how much an area changes for a given year. The geomedian part of the product provides an "average" cloud-free image over the given year. The geomedian image is calculated with a multi-dimensional median, using all the spectral measurements from the satellite imagery at the same time in order to maintain the relationships among the measurements. The median absolute deviation part of the product uses three measures of variance, each of which provides a 'second order' high dimensional statistical composite for the given year. The three variance measures show much an area varies from the "average" in terms of 'distance' based on factors such as brightness and spectra: Euclidean distance (EMAD) Cosine (spectral) distance (SMAD) Bray Curtis dissimilarity (BCMAD) Together, they provide information on variance in the landscape over the given year and are useful for change detection applications.
