The data represents the Enhanced Vegetation Index (EVI), derived from Near-IR, Red, and Blue bands, with values ranging from -1.0 to 1.0. Composites are created using all scenes per year, with the most recent pixel. The dataset is deprecated and is complete since the USGS stopped producing Pre-Collection Landsat data as of May 1, 2017. Users should switch to Collection 1-based datasets.\n"]]
