Composites are built from 32-day periods, using the most recent pixel value. The USGS stopped producing this Pre-Collection Landsat on May 1, 2017. Users should switch to a Collection 1-based dataset, specifically the LANDSAT/LT04/C01/T1_32DAY_TOA, which supersedes this one. Data is 30m resolution, and free for research, education, and nonprofit use.\n"]]
