  • Estimating ground cover via spectral data

    Creator:
    Axness, Daniel S.
    Abstract:
    Potato ground cover and spectral data were measured in the Columbia Basin during the 1990 growing season. Three spectral were correlated with ground cover; normalized difference, near infrared-red ratio, and the first derivative of the spectral curve at 750 nm. All models were statistically significant at the 99% level. Normalized...

  • Experimental and analytical characterization of bidirectional reflectance data for engineering materials

    Creator:
    Zaworski, Joseph Robert
    Abstract:
    Bidirectional reflectance is a fundamental property used for the analysis of radiative heat transfer. It is a form of reflectivity in which the spectral and directional dependencies of both the beam incident on a surface and the beam reflected from the surface are specified. A new system has been designed...
