The data uses Tier 1 orthorectified scenes with top-of-atmosphere reflectance. Composites are created from 8-day periods, using the most recent pixel for the composite value. The Normalized Difference Vegetation Index (NDVI), calculated from Near-IR and Red bands, ranges from -1.0 to 1.0 with 30-meter pixel resolution. The data is provided by Google and is free to use for research, education, and non-profit purposes.\n"]]
