Munsell soil color chart: a spectral reflectance dataset

This dataset contains the calculated spectral reflectance of the 2009 edition of Munsell soil colour chart measured using Konika Minolta 2000 spectroradiometer with a tungsten lamp as the light source. The spectroradiometer has a 380-780nm spectral range with a 1nm spectral sampling. Reflectance is obtained by using the following equation with the assumption of a uniformly-illuminated surface.<br> \(R(\lambda) = \frac{\Phi(\lambda)_{Reflected}}{\Phi(\lambda)_{Incident}} \) \( \Phi(\lambda)_{Incident} = \frac{\Phi(\lambda)_{sample}}{R(\lambda)_{sample}} \)<br> using a known \(R(\lambda)\) of white reference tile used to obtain \(\Phi(\lambda)_{Incident}\) of the tungsten lamp.
