Access to the Santa Barbara Asphalt Road Spectral Library

The spectra are available as MS Excel worksheets for both Fairview Ave and Cathadral Oaks:

The names/numbering of the spectra are conform with the visual examples shown in the interactive map. The values are in reflectance as parts of one (0.5=50 % reflectance). The spectral measurements range from 350-2450 nm (bandwith 1 nm). The major water vapor absorption bands (1340-1450 nm and 1790-1970 nm) have been deleted. No noise removal or any related modifications have been performed and every user of the library should consider that. Pictures of the field spectra acquistions can be found here. Since there is not much information availble on understanding asphalt road spectra, here is a document with spectra examples and interpretations from the Santa Barbara Road Spectral Library.
