LANDSAT-8 SATELLITE IMAGERY
LANDSAT-8, launched in February 11, 2013, is a medium resolution optical satellite aiming to provide data for applications in agriculture, education, business, science and the government. It is considered an improvement of its predecessor, LANDSAT-7, with its enhanced capabilities to monitor water quality and high atmospheric clouds.
The satellite comprises two sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).
The satellite comprises two sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).
OLI consists of 9 spectral bands ranging through the visible, near-infrared and shortwave radiation spectrum. With the spatial resolution ranging from 15 to 30m (see table 1), LANDSAT-8 provides quality satellite imagery which can depict different land uses from space.
TIRS is comprised of two spectral bands which detect thermal infrared, a vital tool to measure the temperature of the Earth’s surface.
