The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are onboard the Landsat 8 satellite, have acquired images of the Earth since February 2013. The sensors collect images of the Earth with a 16-day repeat cycle, referenced to the Worldwide Reference System-2. The approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi). Landsat 8 image data files consist of 11 spectral bands with a spatial resolution of 30 meters for bands 1-7 and bands 9-11; 15-meters for the panchromatic band 8. Delivered Landsat 8 Level-1 data typically include both OLI and TIRS data files; however, there may be OLI-only and/or TIRS-only scenes in the USGS archive. A Quality Assurance (QA.tif) band is also included. This file provides bit information regarding conditions that may affect the accuracy and usability of a given pixel – clouds, water or snow, for example.

Landsat.org, an affiliate of the Tropical Rain Forest Information Center (TRFIC), now hosts the Global Orthorectified Landsat Datasets for four epochs: 1970's MSS, 1990's TM, 2000's ETM+, and 2005's ETM+. We provide access to these data for the global community of users for FREE.

Dry season cloud free Landsat imagery (30m ground pixel) is combined annually to provide a whole of Western Australia imagery mosaic. These mosaics start in 1988 to current day providing data for time series analysis and whole of state imagery. Click here for more information.

The USGS Earth Resources Observation and Science (EROS) Center archive holds data collected by the Landsat suite of satellites, beginning with Landsat 1 in 1972. All Landsat data held in the USGS EROS archive are available for download at no charge.

Global Land Survey 1975 images were acquired from 1972 to 1987 by Landsat 1-5 MSS. Landsat 4-5 data were used to fill gaps in the Landsat 1-3 data. The U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) collaborated on the creation of the global land datasets using Landsat data from 1972 through 2008. Each of these global datasets was created from the primary Landsat sensor in use at the time: the Multispectral Scanner (MSS) in the 1970s, the Thematic Mapper (TM) in 1990, the Enhanced Thematic Mapper Plus (ETM+) in 2000, and a combination of TM and ETM+, as well as EO-1 ALI data, in 2005.
