WebThe Red-Edge NDVI is a vegetation index for estimating vegetation health using the red-edge band. It is especially useful for estimating crop health in the mid to late stages of growth, during which the chlorophyll concentration is relatively higher. WebRed-edge Chlorophyll Index is used to detect chlorophyll content in plants, which makes it most relevant during the active growth stages. There are plenty of online tools that have already built-in algorithms to measure different vegetation indices. All farmers have to do is open the app and check the values.

WebThe Red-Edge NDVI (NDVIre) method is a vegetation index for estimating vegetation health using the red-edge band. It is especially useful for estimating crop health in the mid to late stages of growth, when the chlorophyll concentration is relatively higher. WebLeaf area index (LAI) is a crucial biophysical variable for agroecosystems monitoring. Conventional vegetation indices (VIs) based on red and near infrared regions of the electromagnetic spectrum, such as the normalized difference vegetation index (NDVI), are commonly used to estimate the LAI.
