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.
Our Spaceye product uses the red and near infrared spectral bands from various satellites (Landsat 8 OLI, Landsat 5 TM, Sentinel 2 MSI) to calculate the AVI with the following formulas (one for each satellite):
Our AVI product is produced for the whole globe from 1985 to today with timely temporal resolution!
