Table 1 Description and wavelength ranges (in micrometres) of the spectral bands of the sensors aboard the three Landsat satellites used in this study. The Landsat-8 OLI sensor has a higher radiometric resolution of 12-bit resulting in higher dynamic range and a greater ability to characterise land cover state and condition.
