The Landsat 8 mission was a collaboration between the National Aeronautics and Space Administration (NASA) and the United States Geological Survey (USGS) which ensures the continued availability of Landsat data. This dataset collection contains moderate resolution images of the Earth’s surface in the visible to thermal infrared. Landsat 8 carries two science instruments: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). The OLI provides measurements in the visible, near infrared and shortwave infrared including a panchromatic band with 15 m spatial resolution and multispectral bands with 30 m spatial resolution. The TIRS provide a new infrared channel (band 9) for cirrus detection and a new deep blue band (band 1) for coastal monitoring. The TIRS instrument provides measurements at 100 m resolution in two bands in the thermal infrared previously covered by a single wide band. Some data from 2014 is now held by the Centre for Environmental Data Analysis (CEDA).

The Landsat Thematic Mapper (TM) sensor was carried onboard Landsats 4 and 5 from July 1982 to May 2012 with a 16-day repeat cycle, referenced to the Worldwide Reference System-2. Very few images were acquired from November 2011 to May 2012. The satellite began decommissioning activities in January 2013. The Thematic Mapper (TM) is an advanced, multispectral scanning, Earth resources sensor designed to achieve higher image resolution, sharper spectral separation, improved geometric fidelity, and greater radiometric accuracy and resolution than the Multispectral Scanner (MSS) sensor. TM data are sensed in seven spectral bands simultaneously. A TM scene has an Instantaneous Field Of View (IFOV) of 30m x 30m in bands 1-5 and 7 while band 6 has an IFOV of 120m x 120m on the ground (band 6 was collected at 120 meters, but was resampled to 30 meters). Band 6 senses thermal (heat) infrared radiation. Landsat can only acquire night scenes in band 6. The approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).

Landsat 8 was a joint project between the National Aeronautics and Space Administration (NASA) and the United States Geological Survey (USGS). Data was originally obtained from the USGS via the Catapult Satellite Applications Facility and is now held by Centre for Environmental Data Analysis (CEDA). The data are in GeoTIFF format. This Landsat 8 dataset corresponds to the standard Level 1 terrain corrected data compatible with data acquired using Landsat 1 to Landsat 7. The Landsat 8 payload comprises two sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). The OLI provides measurements in the visible, near infrared and shortwave infrared at 30 m spatial resolution (bands 1-7 and 9), as well as in a panchromatic band (band 8) at 15 m spatial resolution. The OLI provides a new infrared channel (band 9) for cirrus detection and a new deep blue band (band 1) for coastal monitoring. The TIRS instrument provides thermal infrared measurements in two bands (bands 10 and 11) at 100 m spatial resolution resampled to 30 m to match the OLI multispectral bands. The images are in North up (MAP) orientation. The data is supplied using the Universal Transverse Mercator (UTM) map projection. Polar Stereographic projection is used for polar scenes. The dataset uses the World Geodetic System (WGS) 84 datum. Pixel values are 16 bit. Data is catalogued according to path and row number according to the Worldwide Reference System 2 (WRS-2).
