5 For the images in Fig. 2-14, the Briones Reservoir is a good choice for a dark object (it is significantly darker than the San Pablo Reservoir at shorter wavelengths). Averaging the darkest pixels in the Reservoir yields DNs of 53, 20, 11, and 14 for bands 1 through 4. It is ...
These tend to incorporate the near-infrared (NIR) and shortwave infrared (SWIR) wavelengths such as TM/ETM+ band 5, OLI band 6, NBR, NDVI and EVI, given they often have strong relationships with observed AGB values [10,85]. The TC transformations, including TCB (overall reflectance), TCG...
According to the spectral response recorded by the training areas, all the classes exhibit a general trend that matches how we would expect the light to be absorbed in water, with a stronger reflectance in the green band, which gradually becomes weaker in the longer wavelengths, due to the ...
, to replace the aging Landsat 7 satellite and work with Landsat 8. The satellite has scientific instruments — the Operational Land Imager 2 (OLI-2) and the Thermal Infrared Sensor 2 (TIRS-2) — together aiming to detect minute surface changes through analysis of multiple light wavelengths....
Near Infrared(Band 5), or NIR, is especially important for vegetation because growing plants reflect it – the water in their leaves scatter the wavelengths back into the sky. This enables a more precise measurement of plant health than possible with natural color. ...
