This layer shows the NDVI calculated using the spectral information from a hyperspectral camera (Headwall – Nano) recorded with a drone over the vineyard on July 30, 2020. NDVI (= Normalized Difference Vegetation Index) belongs to the vegetation indices, which can map the vitality of plants by using spectral information in the red and near-infrared. It has a defined value range and can be easily interpreted as healthy vegetation has values from 0.6 to 1 maximum.
