GNDVI: Green Normalized Difference Vegetation Index

In VegSpecIndex: Vegetation and Spectral Indices for Environmental Assessment

Green Normalized Difference Vegetation Index

Description

Green Normalized Difference Vegetation Index (GNDVI) is modified version of NDVI to be more sensitive to the variation of chlorophyll content in the crop. The highest correlation values with leaf nitrogen content and DM were obtained with the GNDVI index in all data acquisition periods and both experimental phases. GNDVI was more sensible than NDVI to identify different concentration rates of chlorophyll, which is highly correlated at nitrogen, in two species of plants (EOS, 2022).
