This research compared the variability/diversity of spectral information captured with spectrometers at the airborne, field, and leaf level to tree species diversity. Airborne measurements were made over the North Saskatchewan River Valley while field and leaf measurements were done with synthetic tree plots on the roof of the Biological Sciences building, University of Alberta. Measures of optical diversity (spectral variables), such as the standard deviation in vegetation indices, principal components, and slope analysis, showed significant correlation to species diversity indices. The strongest correlations (R 2: ODI... |
