Landsat 8 or Landsat Data Continuity Mission, LDCM, was launched in February, 2013 to collect data and satellite imagery to be applied in the following fields: agriculture, government, education. Landsat 8 is equipped with two sensors: OLI (Operational Land Imager) – the scanning radiometer working in multi channels and TIRS (Thermal Infrared Sensor) – IR radiometer, working in 2 channels.
OLI acquires imagery at nine wavelengths, operating in the range of 0.433-2.300 μm. It obtains images at 15 m resolution, which can be used for cirrus clouds studying and water quality control. TIRS obtaines pictures in two infrared wavelength at 100m resolution. These Landsat 8 images are employed for heat and moisture observation and surface temperature control within the defined areas. Both sensors are capable of scanning along the path of satellite, thereby it helps to decrease distortion in comparison with the previous Landsat images, obtained by transverse scanning technology. Nevertheless, Landsat 8 data products are consistent with other Landsat data products of Level-1.
