Geoscience Australia Landsat 9 OLI TIRS Analysis Ready Data Collection 3

Purpose

This product takes Landsat 9 imagery captured over the Australian continent and corrects for inconsistencies caused by atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. The imagery is captured using the Operational Land Imager (OLI) and Thermal Infra-Red Scanner (TIRS) sensors aboard Landsat 9. Only the OLI data is included in this product, while the TIRS data is used in processing, particularly in identification of clouds. This product is a single, cohesive Analysis Ready Data (ARD) package, which allows you to analyse surface reflectance data as is, without the need to apply additional corrections.
