Index generator

To generate predefined indices based from the imported images.

1. Click the tab Index generator.
2. Select the required Source layer from the menu.
3. A selection of indices is available to generate based on the source layer data type.
4. Check/uncheck the indices required.
5. Click GENERATE.

Available indices

Index Description Formula Image import type
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
LCI - Leaf Chlorophyll Index Index to assess chlorophyll content in areas of complete leaf coverage. (NIR − REDEDGE) + (NIR − RED) Multispectral
MCARI - Modified Chlorophyll Absorption in Reflective Index Index used to measure chlorophyll concentrations including variations in the Leaf Area Index. 1.2 * (2.5 * (NIR - RED) - 1.3 * (NIR - GRE)) 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 − REDEDGE) / (NIR + REDEDGE) Multispectral
NDVI - Normalized Difference Vegetation Index Generic index used for leaf coverage and plant health. (NIR − RED) / (NIR + RED) 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
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
