Table 5 Correlation between repeated measurements from Handheld ASD for two different vegetation indices

From: Application of unmanned aerial systems for high throughput phenotyping of large wheat breeding nurseries

Green normalized difference vegetation index; GNDVI (Canon S100) 0.62
Red-edge normalized difference vegetation index; RENDVI (MultiSpec 4C) 0.88
  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
