Available indices

Index Description Formula Image import type
NDVI - Normalized Difference Vegetation Index Generic index used for leaf coverage and plant health. (NIR − RED) / (NIR + RED) Multispectral
NDRE - Normalized Difference Red Edge Index sensitive to chlorophyll content in leaves against soil background effects. This index can only be formulated when the red edge band is available. (NIR − RED-EDGE) / (NIR + REDEDGE) Multispectral
SIPI2 - Structure Intensive Pigment Index 2 Index used in areas with high variability in canopy structure (e.g. forestry). (NIR − GREEN) / (NIR − RED) Multispectral
LCI - Leaf Chlorophyll Index Index to assess chlorophyll content in areas of complete leaf coverage. (NIR − REDEDGE) + (NIR − RED) Multispectral
TGI - Triangular Greenness Index RGB index for chlorophyll sensitivity. GREEN − (0.39 * RED) − (0.61 * BLUE) RGB
VARI - Visible Atmospherically Resistant Index RGB index for leaf coverage. (GREEN − RED) / (GREEN + RED − BLUE) RGB, MicaSense
BNDVI - Blue Normalized Difference Vegetation Index NDVI index without red channel availability, for areas sensitive to chlorophyll content. (NIR − BLUE) / (NIR + BLUE) Multispectral (excluding Sequoia)
GNDVI - Green Normalized Difference Vegetation Index NDVI index without red channel availability, for areas sensitive to chlorophyll content. (NIR − GREEN) / (NIR + GREEN) Multispectral
