Using Landsat Data FAQs - 15 Found

What are the best Landsat spectral bands to use for my study?

This is a common question considered by all users of remotely sensed data. The level of detail (spatial resolution) is often the most interesting aspect of viewing a satellite image, but less appreciated is how changes in irradiative energy reflected by different surface materials are used to identify features of interest.

 

Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)

 

BandWavelengthUseful for mapping
Band 1 – coastal aerosol0.43-0.45coastal and aerosol studies
Band 2 – blue0.45-0.51Bathymetric mapping, distinguishing soil from vegetation and deciduous from coniferous vegetation
Band 3 - green0.53-0.59Emphasizes peak vegetation, which is useful for assessing plant vigor
Band 4 - red0.64-0.67Discriminates vegetation slopes
Band 5 - Near Infrared (NIR)085.-0.88Emphasizes biomass content and shorelines
Band 6 - Short-wave Infrared (SWIR) 11.57-1.65Discriminates moisture content of soil and vegetation; penetrates thin clouds
Band 7 - Short-wave Infrared (SWIR) 22.11-2.29Improved moisture content of soil and vegetation and  thin cloud penetration
Band 8 - Panchromatic.50-.6815 meter resolution, sharper image definition
Band 9 – Cirrus1.36 -1.38Improved detection of cirrus cloud contamination
Band 10 – TIRS 110.60 – 11.19100 meter resolution, thermal mapping and estimated soil moisture
Band 11 – TIRS 211.5-12.51100 meter resolution, Improved thermal mapping and estimated soil moisture

Landsat Multi Spectral Scanner (MSS)

 


Landsat MSS 1, 2,3  Spectral Bands
Landsat MSS 4,5 Spectral BandsWavelengthUseful for mapping
Band 4 - greenBand 1 - green0.5-0.6Sediment-laden water, delineates areas of shallow water
Band 5 - redBand 2 - red0.6-0.7Cultural features
Band 6 - Near InfraredBand 3 - Near Infrared0.7-0.8Vegetation boundary between land and water, and landforms
Band 7 - Near InfraredBand 4 - Near Infrared0.8-1.1Penetrates atmospheric haze best, emphasizes vegetation, boundary between land and water, and landforms

 

The Spectral Characteristics Viewer is an interactive tool developed by scientists at the USGS Earth Resources Observation and Science (EROS) Center to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), one can determine which bands of the selected sensor will work for the application.
