The composites, available from 1982 to 1993, calculate the Normalized Difference Vegetation Index (NDVI) from Near-IR and Red bands, ranging from -1.0 to 1.0. Composites are created over 32-day periods, with the most recent pixel value used. The data, provided by USGS, is in the public domain and should be cited accordingly. The dataset has been superseded by another.\n"]]
