R Documentation

Compute NDVI from Phenocam color indices

This function computes camera NDVI as in Petach et al. (2014)

NDVI(exposure.matched, RGB.VI, IR.VI, spatial=FALSE)

`exposure.matched`	A dataframe as in output from `matchExposure()`
`RGB.VI`	A dataframe for RGB VI extracted as in output from `extractVIs()`
`IR.VI`	A dataframe for IR VI extracted as in output from `extractVIs()`
`spatial`	Set this flag to TRUE if you have extracted VIs with spatial == TRUE.

Compute NDVI as in Petach et al. (2014)

A data.frame with NDVI computed after Petach et al. (2014).
