How many spectral bands does Landsat 8 have?
Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9.
What are the bands of Landsat 8?
Landsat 8 bands from the OLI sensor are coastal, blue, green, red, NIR, SWIR-1, SWIR-2 and cirrus. These 8 bands have a ground resolution of 30 meters. Then, the panchromatic band has a finer resolution of 15 meters.
What is the spectral resolution of Landsat 8?
Landsat 8 images have 15-meter panchromatic and 30-meter multi-spectral spatial resolutions along a 185 km (115 mi) swath.
What does Landsat 8 measure?
Landsat 8 (formerly the Landsat Data Continuity Mission, LDCM), a collaboration between NASA and the U.S. Geological Survey, provides moderate-resolution (15 m–100 m, depending on spectral frequency) measurements of the Earth’s terrestrial and polar regions in the visible, near-infrared, short wave infrared, and …
What are the best Landsat spectral bands for use in my research?

What are spectral bands in remote sensing?
A spectral band is a matrix of points defined by three dimensions, its coordinates and the intensity relating to the radiance. From: Optical Remote Sensing of Land Surface, 2016.
What is the resolution of the spectral bands?
Spectral resolution describes the ability of a sensor to define fine wavelength intervals. The finer the spectral resolution, the narrower the wavelength range for a particular channel or band. Black and white film records wavelengths extending over much, or all of the visible portion of the electromagnetic spectrum.
What is the meaning of spectral band?
British Dictionary definitions for band spectrum band spectrum. noun. a spectrum consisting of a number of bands of closely spaced lines that are associated with emission or absorption of radiation by molecules.
What band is blue, green red Landsat 8 image?

What is meant by spectral bands?
What do spectral bands do?
Spectral bands are part of optical spectra of polyatomic systems, including condensed materials, large molecules, etc. Each line corresponds to one level in the atom splits in the molecules. When the number of atoms is large, one gets a continuum of energy levels, the so-called “spectral bands”.
