Each annual composite includes all scenes from that year, selecting the \"greenest\" pixel based on the highest Normalized Difference Vegetation Index (NDVI). The USGS no longer produces Pre-Collection Landsat as of May 1, 2017; thus the dataset is complete, and users are advised to use the LANDSAT/LT05/C01/T1_ANNUAL_GREENEST_TOA collection.\n"]]
