Landsat Collections ensure that all Landsat Level-1 products contain known data quality.

Previous Landsat Collections
In 2016, the USGS reorganized the Landsat archive into a tiered collection management structure titled Landsat Collection 1. This structure ensures that all Landsat Level-1 products provide a consistent archive of known data quality while controlling continuous improvement of the archive and access to all data as they are acquired. The implementation of collections represents a substantial change in the management of the Landsat archive by ensuring consistent quality through time and across all instruments. Collection 1 contains all Level-1 data acquired since 1972 to present from Landsat 1-8. Landsat 9 is only available in Collection 2.
NOTE: Landsat Collection 1 data and products are no longer available to download from the USGS as of December 30, 2022. Landsat Collection 2 remains available. Please access the Landsat Collection 2 webpage for information about Collection 2 data and science products.
Landsat Collection 2 marks the second major reprocessing event of the USGS Landsat Level-1 archive, resulting in several product improvements that harness recent advancements in data processing, algorithm development, and data access and distribution capabilities. A primary characteristic of Collection 2 is the substantial improvement in the absolute geolocation accuracy of the global ground reference dataset used in the Landsat Level-1 processing flow. Additionally, Collection 2 includes updated global digital elevation modeling sources, calibration and validation updates, as well as global Level-2 surface reflectance and surface temperature scene-based products from 1982 to present. Collection 2 contains all Landsat sensors Landsat 1-9.
