Landsat Collections: Providing a Stable Environmental Record for Time Series Analysis
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.

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...
Why are some Landsat browse images black?
Black browse images are night (ascending) scenes, which are occasionally acquired for WRS-2 rows 123 to 246. Ascending scenes are available to download. Learn more: How to search and download ascending Landsat scenes
Why is there so much color variation among the Landsat browse images?
A custom color stretch is performed on the images, based on individual scene content. Scenes from within the same area and/or acquisition date might vary in band content (due to differences such as cloud content or ground moisture). This differing content will cause variation in the results of the color stretch. Pixelation is an artifact of the browse generation process and is common for scenes...
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 is the naming convention for Landsat Collection 2 Level-1 and Level-2 scenes?
The naming convention for Landsat Collection 2 Level-1 products remains the same as in Collection 1 . While most of Landsat Collection 2 scenes are produced to both Surface Reflectance (SR) and Surface Temperature (ST), a small number of scenes cannot be processed to ST due to missing auxiliary data. The naming convention of Landsat Collection 2 Level-2 products indicates the data included for...
How do I search and download Landsat Collection 2 data products?
Search Landsat Collection 2 Level-1 and Level-2 products using EarthExplorer , which is the primary portal used to search all data held in the USGS EROS archives . While 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...
