To calculate the index, it is necessary to know the indicators of light reflection both in the infrared area and in the visible, for which it is necessary to get a shot with the help of the BPL. The first indicator has the NIR, the second is the RGB. NDVI, according to the formula, is equal to the differences of these sizes, divided into their sum. With the help of the data regarding the normalized vegetation index, the density of the plants that grow on the daniac area can be calculated, as well as the level of their similarity and approximate height. It is used to diagnose the level of productivity of the fields.
