DVI: Difference Vegetation Index

In VegSpecIndex: Vegetation and Spectral Indices for Environmental Assessment

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.

Usage

DVI (NIR, RED)

Arguments

NIR	Near-infrared spectral band
RED	Red spectral band
