Each annual composite includes all scenes from that year, with the most recent pixel as the composite value. The USGS ceased production of Pre-Collection Landsat on May 1, 2017, marking this collection as complete and recommends transitioning to a Collection 1-based dataset. Data is in the public domain. The dataset has been superseded and must be replaced.\n"]]
