The primary objective of this
studywas the validation of seasonal relationships between field-measured LAI, using a LI-COR 2200 plant canopy
analyzer (PCA), and four red edge and non-red edge satellite-derived spectral vegetation indices (SVIs) of 10 high
spatial resolution Rapid Eye images: the normalized difference vegetation index (NDVI), the red edge NDVI
(NDVI-RE), the modified red edge simple ratio (mSR-RE), and the curvature.
