The Normalized Difference Vegetation Index (NDVI) is calculated using Near-IR and Red bands, with values ranging from -1 to 1. Composites are created yearly, including all images from that year, with the most recent pixel used. This collection covers 1982-1993 and is now complete and deprecated, users should now switch to Collection 1-based datasets. Data is public domain and free for research, education, and nonprofit use.\n"]]
