GLS2005 contains 9500 orthorectified satellite images collected from 2004-2007. The other four are Landsat 5 datasets, split into MSS and TM data, and further categorized into Tier 1 and Tier 2. Tier 1 datasets represent the highest quality for time-series analysis, while Tier 2 includes lower-quality scenes that didn't make the Tier 1 cut. All these datasets represent scaled, calibrated at-sensor radiance data.\n"]]
