Mission and sensor parameters
Launched in 2013, Landsat-8 is an operational earth imaging satellite which is part of joint USGS and NASA-led Landsat programme. It represents the first flight unit of the Landsat Data Continuity Mission (LDCM) programme. Landsat-8 payload consists of two Earth observing sensors: the Operational Land Imager (OLI) and the Thermal Infra-Red Scanner (TIRS) instruments.
