As reported on September 17, 2021, the USGS is retiring the original LandsatLook 1.0 (now LandLook) and Sentinel2Look viewers at the end of the work day on Thursday, October 14, 2021.
Reminder: Historic Prototype Viewers to be Decommissioned
For Landsat Collection 2, users are encouraged to use the new LandsatLook 2.0 tool. The new tool allows rapid online visualization and access to the Landsat archive. It also enables users to create dynamic custom mosaics using three band combinations, to select spectral indices, and to perform quality assessment band filtering.
Landsat Collection 1, Landsat Collection 2, and Sentinel 2 data continue to be available for download form EarthExplorer.
