Landsat 5, 7 EO Products

Raw Bands

Band B1
Blue light

Resolution = 30 m/px

Bandwidth = 0.433–0.453 µm

Purpose = scattered by the atmosphere and illuminates material in shadows better than longer wavelengths; penetrates clear water better than other colors; absorbed by chlorophyll, so plants don’t show up very brightly in this band; useful for soil/vegetation discrimination, forest type mapping, and identifying man-made features. 

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B2
Green light

Resolution = 30 m/px

Bandwidth = 0.525-0.605 µm

Purpose = penetrates clear water fairly well, gives excellent contrast between clear and turbid (muddy) water; helps find oil on the surface of water, and vegetation (plant life); reflects more green light than any other visible color; man-made features are still visible.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B3
Red light

Resolution = 30 m/px

Bandwidth = 0.63-0.69 µm

Purpose = limited water penetration; reflects well from dead foliage, but not well from live foliage with chlorophyll; useful for identifying vegetation types, soils, and urban (city and town) features.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B4
Near IR (NIR)

Resolution = 30 m/px

Bandwidth = 0.75-0.90 µm

Purpose = good for mapping shorelines and biomass content; very good at detecting and analyzing vegetation.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B5
Shortwave IR (SWIR)

Resolution = 30 m/px

Bandwidth = 1.55-1.75 µm

Purpose = limited cloud penetration; provides good contrast between different types of vegetation; useful for measuring the moisture content of soil and vegetation; helps differentiate between snow and clouds.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B6
Thermal IR (TIR or LWIR)

Resolution = 60 / 120 m/px*

Bandwidth = 10.4-12.5 µm

Purpose = useful to observe temperature and its effects, such as daily and seasonal variations; useful to identify some vegetation density, moisture, and cover type.

* The thermal band on Landsat 7 (ETM+ sensor) has a spatial resolution of 60 m; it is 120 m on Landsats 5 (TM sensors).

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B7
Another SWIR

Resolution = 30 m/px

Bandwidth = 2.09-2.35 µm

Purpose = limited cloud penetration; provides good contrast between different types of vegetation; useful for measuring the moisture content of soil and vegetation; helps differentiate between snow and clouds.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Band B8
Panchromatic (“pan”)

Resolution = 15 m/px

Bandwidth = 0.52-0.9 µm

Purpose = only Landsat 7 has a 15 m panchromatic sharpening band used to “sharpen” images.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Color Composites

NIR (Near Infra-red, band 5)

In this image, band 2 is displayed in blue, band 3 is displayed in green, and band 4 is displayed in red. This rendition looks rather strange - vegetation jumps out as a bright red because green vegetation readily reflects infrared light energy! It is similar to pictures taken from aircraft when using infrared film; very useful for studying vegetation.

Available styles: Grayscale, Grayscale advanced, Blue/Red, Green/White Linear, Red Temperature, Reflectance, Landsat DN

Custom script: return [B02, B03, B04];

RGB(7,5,4) - Short-wave Infrared

In this SWIR image, band 2 is displayed in blue, band 4 is displayed in green, and band 7 (or 5) is displayed in red. This rendition looks like a jazzed up true color rendition - one with more striking colors.

Available styles: RGB, RGB advanced, Reflectance, Landsat DN

Custom script: return [B07, B05, B04];

True Color

For the true color rendition, band 1 is displayed in the blue color, band 2 is displayed in the green color, and band 3 is displayed in the red color. The resulting image is fairly close to realistic - as though you took the picture with your camera and were riding in the satellite. But it is also pretty dull - there is little contrast and features in the image are hard to distinguish.

Available styles: RGB, RGB advanced, Reflectance, Landsat DN

Custom script: return [B01, B02, B03];
