Vegetation index | Formula |
|---|---|
Normalized Difference Vegetation Index [15] | \({\text{NDVI}} = \frac{{{\text{NIR}} - {\text{Red}}}}{{{\text{NIR}} + {\text{Red}}}}\) |
Green Normalized Difference Vegetation Index [16] | \({\text{GNDVI}} = \frac{{{\text{NIR}} - {\text{Green}}}}{{{\text{NIR}} + {\text{Green}}}}\) |
RedEdge Normalized Difference Vegetation Index [17] | \({\text{RENDVI}} = \frac{{{\text{NIR}} - {\text{RedEdge}}}}{{{\text{NIR}} + {\text{RedEdge}}}}\) |
Soil Adjusted Vegetation Index [18] | \({\text{SAVI}} = \frac{{(1 + {\text{L}}) \times ({\text{NIR}} - {\text{Red)}}}}{{{\text{NIR}} + {\text{Red}} + {\text{L}}}}\) |
Enhanced Vegetation Index [19] | \({\text{EVI}} = \frac{{{\text{G}} \times ({\text{NIR}} - {\text{Red}})}}{{{\text{NIR}} + {\text{c}}_{1} {\text{Red}} - {\text{c}}_{2} {\text{Blue}} + {\text{L}}}}\) |
