Each composite includes all scenes from a given year, using the most recent pixel value. The Enhanced Vegetation Index (EVI), ranging from -1.0 to 1.0, is computed from Near-IR, Red, and Blue bands with 30-meter pixel size. This dataset is now complete and deprecated; users are advised to use the Collection 1-based dataset.\n"]]
