Each year's composite includes all scenes, selecting the \"greenest\" pixel based on the highest Normalized Difference Vegetation Index (NDVI). The USGS has discontinued producing this pre-collection dataset, advising users to switch to Collection 1. The data is public domain and requires USGS acknowledgement when used.\n"]]
