Relative errors of surface reflectance as a function of the wavelength for targets H1–H4.

<p>Relative errors between the uniform Lambertian surface reflectance derived from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066972#pone.0066972.e062" target="_blank">Equation (5</a>) and the non-uniform Lambertian surface reflectance derived from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066972#pone.0066972.e066" target="_blank">Equation (7</a>) and the <i>in situ</i> surface reflectance for targets H1–H4 in bands 13–108.</p>
