Landsat-8 Satellite

Landsat 8 Satellite launched 11 February on the year 2013, from Vandenberg Air Force Base, California on an Atlas-V 401 Rocket from United Launch Alliance. It was developed as a collaboration between NASA and the U.S. Geological Survey (USGS).

The satellite carries of 2 science instruments; i) Operational Land Imager (OLI) and ii) Thermal Infrared Sensor (TIRS). These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR); 100 meters (thermal); and 15 meters (panchromatic). The OLI measures in the visible, near infrared, and shortwave infrared portions of the spectrum. The TIRS measures land surface temperature in thermal bands.
