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 ...
Therefore, Landsat 7 (ETM+, 2000) and Landsat 8 (OLI, 2014) were compared in determining suitable bands suited for geological mapping in the study area. The methodology consist performing principal component and factor loading analysis, IHS transformation and decorrelation stretch of the FCC with ...
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...
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...
Landsat-7 Enhanced Thematic Mapper 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...

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 ...
It is a combination of all Landsat TM or Enhanced Thematic Mapper Plus (ETM+) spectral bands except the thermal band, with the greatest weight given to the SWIR channel (e.g., [14]). While the use of remote sensing for detection of bark beetle infestation is well established, its ...
