ACCESS MISSION DATA

Landsat 8 is an Earth-imaging satellite from NASA which launched in 2013. The Landsat programme provides a global archive of satellite imagery and is managed and operated by the U.S. Geological Survey (USGS).

About Landsat-8

Landsat-8 was launched on 11 February 2013 from Vandenberg Air Force Base, California on an Atlas-V rocket. The satellite is part of the long-running Landsat programme led by USGS and NASA and carries the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).

Landsat-8 is part of ESA's Third Party Missions Programme, in which ESA has an agreement to distribute data products from the mission.

Landsat-8 Objectives

Landsat-8 consists of three key mission and science objectives:

  • collect and archive medium resolution multispectral image data affording seasonal coverage of the global land mass
  • ensure that Landsat-8 data are sufficiently consistent with data from the earlier Landsat missions in terms of acquisition geometry, calibration, coverage characteristics, spectral characteristics, output product quality, and data availability
  • ensure products are available to download within three hours

Landsat-8 Instruments

The Operational Land Imager (OLI) provides two new spectral bands in respect to the Landsat-7 ETM+ instrument, one tailored especially for detecting cirrus clouds (band 9, new Near Infra-Red (NIR) band) and the other for coastal zone observations (band 1, new deep blue visible channel). It measures in the visible, NIR, and Shortwave Infra-Red (SWIR) portions of the electromagnetic spectrum and offers 15 metre panchromatic, and 30 metre multi-spectral spatial resolution.

The Thermal Infrared Sensor (TIRS) was added to the Landsat-8 payload to continue thermal imaging and to support emerging applications such as evapotranspiration rate measurements for water management. TIRS was built by NASA Goddard Space Flight Center, and it has a three-year design life. The 100 m TIRS data is registered to the OLI data to create radiometrically, geometrically, and terrain-corrected 12-bit Landsat-8 data products.
