This graphic displays the timeline of generating Landsat products.
Landsat 9 Collection 2 Level-1 products are delivered within 4-6 hours of acquisition. Landsat 9 Level-2 Surface Reflectance and Surface Temperature products become available in about 3 days.
How long does it take to create Landsat Collection 2 Level-2 products after a Landsat scene is acquired?
Landsat Level-2 Surface Reflectance and Surface Temperature products require Landsat Collection 2 Level-1 scenes that are processed to Tier 1 or Tier 2, as well as additional auxiliary data. The Landsat Collection 2 Product Generation Timeline below gives a graphical view of this typical product generation timeframe.

What are Cloud Optimized GeoTIFFs (COGs)?
A Cloud Optimized GeoTIFF (COG) is a GeoTIFF file with an internal organization that enables more efficient workflows in the cloud environment. It does this by leveraging the ability of clients issuing HTTP GET range requests to ask for just the parts of a file they need.

How do Landsat Collection 2 Level-2 products compare with products from Collection 1?
Landsat Collection 2 Level-2 Surface Reflectance and Surface Temperature science products are scene-based, produced within the standard processing system, and available to download directly from EarthExplorer. Collection 2 Level-2 products are available for Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI/TIRS data acquired from 1982 to present. Landsat MSS 1-5 data are not currently available...
How do I search and download Landsat Collection 2 data products?
Landsat Collection 2 Level-1 and Level-2 products can be searched using EarthExplorer, the primary portal used to search all data held in the USGS EROS archives. Landsat Collection 2 products are processed and stored in the USGS Cloud Hosting Solution (CHS) environment; downloads are managed through EarthExplorer. The USGS Landsat no-cost open data policy remains intact since its inception in 2008...
What are Landsat Collection 2 Full Resolution Browse Images?
Similar to Landsat Collection 1 LandsatLook Images, the Landsat Collection 2 Full Resolution Browse Images are .JPG and .TIF images with geographic referencing that are compressed and stretched to create an image optimized for image selection and visual interpretation. They are derived from Landsat Collection 2 Level-1 data and are available to download from EarthExplorer. Learn more: Landsat Full...
Why are the fill values and scaling factors of Landsat Collection 2 Level-2 products different from those products in Collection 1?
The fill values and scale factors of Landsat Collection 2 Level-2 products were updated to be consistent with that of Landsat Collection 2 Level-1 data, while using the unsigned integer data type more efficiently. As shown in the table below, the fill value of the Surface Reflectance and Surface Temperature bands were changed from “-9999” in Collection 1, to “0” in Collection 2 to be consistent...
What updates were made in Landsat Collection 2?
Landsat Collection 2 marks the second major reprocessing event of the USGS Landsat archive. Continuing the tiered collection management structure implemented in Landsat Collection 1, Landsat Collection 2 introduces several advancements in data processing, algorithm development, as well as data access and distribution capabilities, including: Improved per-pixel geodetic accuracy by incorporating...
