Crop Health Indexes
Crop health indexes provide information of plant physical structure and plant cover.
NDVIIndicator of vegetation greenness and growth.
NIRVReflects the productivity and yield of the crops as closely as possible.
NDWIIndicator of water stress and irrigation practices.
EVISimilar to SAVI, tries to reduce noise in NDVI and resolves saturation issues at high LAI, closer related to plant productivity (gross primary production GPP). How advantageous depends on the crop type.
CHIChlorophyll content Index, ideal for monitoring biotic stress, yield estimation and Nitrogen requirements.
NDRENormalized Difference Red Edge Index for NITROGEN stress monitoring.
LAICommonly measured in fields, used in crop models to predict yield.
SAVIEssentially, NDVI corrected for noise coming from soil.
RGBTrue color image, used as visual check on customer side for any odd patterns in the indexes.
