    • Spectral reflectance data of rock and soil in southcentral Alaska

    Metadata Updated: July 6, 2024

    An ASD FieldSpec 4 Hi-Res NG Spectroradiometer was used to collect the reflectance properties of soil and rock in southcentral Alaska, USA around the city of Anchorage and the Prince William Sound. Reflectance is a property of the material being observed, being the ratio of the amount of light leaving a target to the amount of light striking the target. Reflectance is a unitless value from 0 to 1, where a value of 0 indicates that the material absorbs all energy and 1 indicates total reflectance. Additionally, samples were collected from the field and later measured using the spectrometer in the laboratory. Both field and laboratory data were collected in the summer and fall of 2022.
