Abstract: This data set is a raster file containing global information for bands 1 through 11 for Landsat 8 Operational Land Imager (OLI) and Thermal Land Imager (TIRS).
Purpose: The mission of the Landsat 8 satellite is to provide a vehicle for continuing
the flow of global change information to users worldwide. The Landsat 8
satellite fulfills its mission by providing repetitive, synoptic coverage of
continental surfaces and by collecting data in spectral bands that include the
visible, near-infrared, shortwave, and thermal infrared portions of ... the
electromagnetic spectrum. Landsat 8 mission objectives include:
1) Maintaining Landsat data continuity by providing data that are
consistent in terms of data acquisition, geometry, spatial resolution,
calibration, coverage characteristics, and spectral characteristics with
previous Landsat data.
2) Generating and periodically refreshing a global archive of substantially
cloud-free, Sun-lit, land-mass imagery.
3) Continuing to make remote sensing satellite data available to domestic
and international users and expanding the use of such data for global change
research in both the Government and private commercial sectors.
4) Promoting interdisciplinary research via synergism with other EOS
observations, specifically, orbiting in tandem with the EOS Terra satellite for
near coincident observations.
The Landsat 8 satellite is another step in the development and application of
remotely sensed satellite data for use in managing the Earth's land resources.
Improving upon earlier Landsat systems, the OLI and TIRS sensors aboard Landsat 8, provide for new capabilities in the remote sensing of Earth's land surface. Landsat 8 data are collected from a nominal
altitude of 705 kilometers in a near-polar, near-circular, Sun-synchronous
orbit at an inclination of 98.2 degrees, imaging the same 183-km swath of
Earth's surface every 16 days. Additional information can be found at the following sites:

Data Set Credit:
The Landsat Program, as defined by Congress in 1992 and amended by Presidential
Decision Directive/NSTC-3 in May 1994, is managed cooperatively by the National
Aeronautics and Space Administration (NASA), and the USGS. Responsibility for
construction of the spacecraft and instrument lies with NASA. The Landsat
Program is part of NASA's Earth Observing System global change initiative
administered by NASA's Earth Science Enterprise. Data processing, archiving,
and distribution are performed by the USGS. The primary ground station, the
data handling facility and archive are located at the USGS EROS Center in
Sioux Falls, SD. The ground system is able to
distribute Landsat data within 24 hours of its reception at the EROS Center.

Panchromatic band 8 has a resolution of 15 meters. ...
Landsat 8 data are collected from a nominal altitude of 705
kilometers in a near-polar, near-circular, Sun-synchronous orbit at an
inclination of 98.2 degrees, imaging the same 183-km swath of the
Earth's surface every 16 days. The pixels representing the bands for
the image are in the data set only once.
The OLI and TIRS sensors aboard Landsat 8 are nadir-viewing, multispectral
pushbroom radiometers that detect spectrally filtered radiation from
several portions of the electromagnetic spectrum while orbiting Earth
from an altitude of 705 kilometers. Nominal ground sample distances or
pixel sizes include 30 meters each for the eight visible, near-infrared,
and shortwave infrared bands, 100 meters for the thermal infrared bands,
and 15 meters for the panchromatic band. Landsat 8 Wavelength (micrometers)
Band 1 0.43-0.45, Band 2 0.45-0.51, Band 3 0.53-0.59, Band 4
0.64-0.67, Band 5 .85-.88, Band 6 1.57-1.65, Band 7 2.11-2.29,
Band 8 .50-.68, Band 9 1.36-1.38, Band 10 10.6-11.19, Band 11 11.5-12.51.
Data collected by the OLI and TIRS sensors aboard Landsat 8 satellite
are in a raw format, meaning that radiometric and geometric
corrections have not yet been applied to the data. Data collected in
the raw format are level-0 data and equate to a Landsat 8 level-0R
product. When a Landsat 8 Level-0R product is both
radiometrically and geometrically (systematically) corrected, it is
referred to as a Level-1G product. Correction algorithms model the
spacecraft and the sensor, using data generated by onboard computers
during imaging events. A Level-1G product is a geometrically rectified
product that is free from distortions related to the satellite
platform, the sensor, and global Earth characteristics. Distortions
due to Earth's terrain are still present. When a Landsat 8 Level-0R product is
radiometrically and geometrically (systematically) corrected, along with the employment of a digital elevation source for terrain correction, it is
referred to as a Level-1T product.
Access Constraints There are no restrictions to this data set.
Use Constraints There is no guarantee of warranty concerning the accuracy of these data. Users should be aware that temporal changes may have occurred since the data was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of their limitations. Acknowledgement of the originating agencies would be appreciated in products derived from these data. Any user who modifies the data set is obligated to describe the types of modifications they perform. User specifically agrees not to misrepresent the data set, nor to imply that changes made were approved or endorsed by the U.S. Geological Survey.
