Available from 1984 to 2012, it includes seven spectral bands (Blue, Green, Red, NIR, SWIR1, Thermal, SWIR2) and a BQA bitmask. Composites are built with the most recent pixel data from each 8-day period. USGS stopped Pre-Collection Landsat production in 2017, therefore users should use Collection 1-based data. Use of this data requires credit to the U.S. Geological Survey.\n"]]
