The first indication you have data processed meeting Collections specifications is that your data will have a Landsat Product Identifier, not the historical Landsat Scene ID. Along with information inherited from the Scene ID, the Landsat Product Identifier includes the processing level, processing date, collection number, and collection category (bolded below).
| Scene ID | Landsat Product Identifier |
|---|---|
| LXSPPPRRRYYYYDDDGSIVV | LXSS_LLL_PPPRRR_YYYYMMDD_yyyymmdd_CC_TX |
| L = Landsat X = Sensor S = Satellite PPP = WRS path RRR = WRS row YYYY = Year DDD = Julian day of year GSI = Ground station identifier VV = Archive version number |
L = Landsat X = Sensor (C=OLI?TIRS Combined, O=OLI-only, T=TIRS-only, E=ETM+, T=TM, M=MSS) SS = Satellite (07=Landsat 7, 08=Landsat 8) LLLL = Processing correction level (L1TP=Precision Terrain, L1GT=Systematic Terrain, L1GS=Systematic) PPP = WRS path RRR = WRS row YYYYMMDD = Acquisition year (YYYY)/Month (MM)/Day (DD) yyyymmdd = Processing year (yyyy)/Month (mm)/Day (dd) CC = Collection number (01, 02) TX = Collection category (RT = Real-Time, T1=Tier 1, or T2=Tier 2) |

The historical scene ID is listed in the metadata file (MTL.txt) delivered with the Level-1 data product, and is also visible and searchable (along with the Landsat Collection Product ID) in the online metadata on EarthExplorer.

After a Landsat scene is collected, when will it become available for search and download?
Landsat scenes directly downlinked to the USGS EROS Landsat Ground Station become available through EarthExplorer within 6 hours after acquisition, and then become visible in GloVis and the LandsatLook Viewer within 24 hours.Scenes downlinked to other USGS Ground Stations can be available within 1 to 2 weeks. Scenes downlinked to International Ground Stations may become available in the USGS...
How does data from Sentinel-2A’s MultiSpectral Instrument compare to Landsat data?
The Sentinel-2A MultiSpectral Instrument (MSI) data has spectral bands very similar to Landsat 8 (excluding the thermal bands of Landsat 8’s Thermal Infrared Sensor). Learn more: USGS EROS Sentinel-2 Landsat Comparison
What are the processing levels for Landsat Level-1 data?
The table below shows the Landsat Collections Level-1 processing levels:Landsat Level-1 Processing LevelsProcessing LevelDescriptionTerrain Precision Correction (L1TP)Radiometrically calibrated and orthorectified using ground control points (GCPs) and digital elevation model (DEM) data to correct for relief displacement.The highest quality Level-1 products suitable for pixel-level time series...
Does Landsat Level-1 data processing include atmospheric correction?
Landsat Collection 1 Level-1 data are not corrected for atmospheric conditions, however Landsat Science Products, which include Level-2 Surface Reflectance and Provisional Surface Temperature, and Level-3 Burned Area, Dynamic Surface Water Extent, and Fractional Snow Covered Area are atmospherically corrected.Learn more:Landsat CollectionsLandsat Collections Fact sheetLandsat Data Access
Why are two different file naming conventions used in distribution of 3D Elevation Program (3DEP) DEM products?
Updated digital elevation model (DEM) dataset files are now given a name that includes information about the resolution and format of the data. This prevents users from accidentally overwriting existing data that might have different resolutions and formats. For example: an older file: n44w071.zip would now have the name: USGS_13_n44w071.tif indicating 1/3 arc-second elevation data in geotiff...
Are all acquired Landsat scenes held in the USGS Landsat archive?
The USGS archive contains data acquired by the Landsat satellites from 1972 to present.Data is downlinked to various ground stations around the world. While each ground station in the International Cooperator (IC) network is the primary source for distributing the captured data in their area, copies of the data have also been made available to the USGS to place in the Landsat archive for...
I have a list of historical Landsat Level-1 Scene IDs; how can I determine the corresponding Landsat Collections Level-1 Product Identifier?
The historical Landsat Level-1 Scene ID is in the EarthExplorer metadata. After entering a search using the historical Scene ID, the Landsat Level-1 Collection 1 Product Identifier will be returned in the search results. The results can be exported from EarthExplorer in a variety of formats for metadata parsing.We also encourage use of the Bulk Metadata Service to download files that contain both...
What are Landsat Collection Tiers?
Landsat Collection Tiers are the inventory structure for Level-1 data products and are based on data quality and level of processing. The tier definition purpose is to support easier identification of suitable scenes for time-series pixel-level analysis, and provide temporary data that are processed immediately upon downlink to be dispensed quickly in emergency response situations with limited...
What are Landsat Collections?
In 2016, the USGS reorganized the Landsat archive into a tiered collection. This structure ensures that Landsat Level-1 products provide a consistent archive of known data quality to support time-series analyses and data “stacking”, while controlling continuous improvement of the archive and access to all data as they are acquired.Learn more:Landsat Collections Landsat Data Access
