[null,null,[],[],["The Landsat 4 TM dataset, available from 1982-08-13 to 1993-11-17, provides 32-day composites of Tier 1 orthorectified scenes, computed using top-of-atmosphere (TOA) reflectance. Composites are generated by combining all scenes within each 32-day period, with the most recent pixel values used. The dataset includes seven spectral bands (blue to shortwave infrared) and a quality assessment bitmask. Data is free for research, education, and nonprofit use.\n"]]
