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.

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...
