A portion of a Landsat TM scene near Oakland, California, is shown for bands 1 through 4 in Fig. 2-14. These data, although not calibrated for sensor gain and offset (Chapters 3 and 7), nevertheless indicate the general properties of atmospheric influence as a function of wavelength. A ...
30m resolution (6 bands) 60m resolution (1 band) 15m resolution (1 band) Swath width: 183km Uses of the Landsat 7 ETM+ measurements, as well as the historical record obtained from earlier Thematic Mapper (TM) measurements on Landsats 4 and 5, have allowed studies of (i) terrestrial la...
Enhanced Thematic Mapper Plus (ETM+)is a sensor on Landsat-7. It generates 8 spectral bands in blue, green, red, NIR, and mid-infrared (MIR). Bands 1-5 and 7 have a 30-meter resolution. The panchromatic (band 8) has a 15 m resolution. The thermal band has a 60-meter resolution....
Read our Blog to learn how different band combinations are applied to efficiently enhance the visual appearance of the Landsat-8 data
Band combinations using Landsat bands 7-4-2 or 5-4-1 as RGB color images, with color infrared band 4 assigned green for vegetation, generate true-color appearing images. Enhanced lithologic content in the red band results from use of the short-wave infrared bands 7 or 5. We have ...
For the most part, the bands line up with what we’re used to, with some minor tweaking of the spectral ranges. The thermal infrared band from Landsat 7 is now split into two bands for Landsat 8. Whereas before you had one thermal band that was acquired at 60 m resolution (and resamp...

in different standard band combinations. These band combinations include false color (bands 4,3,2)—useful for vegetation studies and crop growth monitoring, natural color with atmospheric penetration (bands 7,4,2)—best suited for analysis of urban studies, and vegetation analysis (bands 5,4,3...
Shortwave Infrared(Bands 6, 7), or SWIR, are particularly useful for telling wet earth from dry earth, and for geology: rocks and soils that look similar in other bands often have strong contrasts in SWIR. Panchromatic(Band 8) works like black and white film. Instead of collecting visible ...
Figure 7 also shows that the “High Turbid Water” class has the highest reflectance value in all the bands, such as a terrestrial class. In addition, the spectral separability between “Deep Water” and shallower “Eelgrass” is obvious in the case of clear water but not when the water ...
