  1. Four measurements were taken on each of 280 plots. To determine repeatability, the first two measurements were averaged and correlated to the average of the second two measurements on a per plot basis across all plots. The VIs presented are band equivalent indices for the Canon S100 (green normalized difference vegetation index; GNDVI) and MultiSpec 4C (red-edge normalized difference vegetation index: RENDVI) used in this study
