This graphic displays the timeline of generating Landsat Collection 2 Level-1 and Level-2 scene-based products.
Landsat Level-1 products
How long does it take to create Landsat Collection 2 Level-2 products after a Landsat scene is acquired?
Landsat Collection 2 Level-2 Surface Reflectance and Surface Temperature products require Landsat Level-1 data that have been processed to Tier 1 or Tier 2 products, 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)? 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.

What are Landsat Collection 2 Full Resolution Browse Images? 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? 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? 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...
