Advanced Vegetation Index
Description
Advanced Vegetation Index (AVI) is a numerical indicator, similar to NDVI that uses the red and near-infrared spectral bands. Like NDVI, AVI is used in vegetation studies to monitor crop and forest variations over time. Through the multi-temporal combination of the AVI and the NDVI, users can discriminate different types of vegetation and extract phenology characteristics/ parameters (Rikimaru et al., 2002)
