Webb26 jan. 2016 · Esun depends on the wavelength and hence the spectral response characteristics of each band and is typically provided by the data supplier. In the case of Landsat 8 OLI, however, USGS and NASA decided not to publish Esun values because they are not required for conversion to reflectance any more. In the following, I will show … WebbIn this case the data value represents the percent reflectance from 0 to 100% for the pixel in each band (wavelength). The Landsat surface reflectance data viewed in this lab is represent by decimals. This means that a value of 1 indicates 100% reflectance at that particular wavelength and value of 0.5 would represent 50% reflectance.
