It is now complete as the USGS discontinued Pre-Collection Landsat production on May 1, 2017. Users should switch to Collection 1 datasets. Composites include all annual scenes, with the most recent pixel as the composite value. The dataset provides multiple bands with varying wavelengths, resolutions, and also a quality assessment band. The dataset is superseded by LANDSAT/LE07/C01/T1_ANNUAL_RAW.\n"]]
