The composites use all available yearly scenes, with the most recent pixel value. Each composite provides the Normalized Difference Vegetation Index (NDVI) band, derived from Near-IR and Red bands, at 30-meter resolution. The data, from the USGS, is public domain and requires proper citation. It is now superseded by a newer dataset.\n"]]
