Difference Vegetation Index
Description
The advantage of the Difference Vegetation Index (DVI) consists in the discrimination of soil from the vegetation biomass (Lemenkova & Debeir, 2023). However, the disadvantage is that it does not considers the difference between the spectral reflectance and radiance of soil surface caused by the atmospheric effects. The use of the DVI is based on the ratio between the NIR and Red spectral bands.
