Can Landsat Collection Real-Time scenes be used in my research?
Landsat Collections Real-Time (RT) data is provided within 12 hours of acquisition in support of the International Charter to help mitigate the effects of disasters on human life and property. The RT tier contains data received from Landsat 8 immediately after acquisition. Estimated radiometric and geometric calibration parameters are applied to these scenes. When final radiometric and geometric...
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.

What is the naming convention for Landsat Collections Level-1 scenes?
The Landsat Collection 1 Level-1 product identifier includes the Collection processing levels, processing date, collection number, and collection tier category: LXSS_LLLL_PPPRRR_YYYYMMDD_yyyymmdd_CC_TX Where: 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) LLL = Processing correction level (L1TP...
What are U.S. Landsat Analysis Ready Data (ARD)?
U.S. Landsat Analysis Ready Data (ARD) are pre-packaged and pre-processed bundles of Landsat data products that make the Landsat archive more accessible and easier to analyze, and reduce the amount of time users spend on data processing for time-series analysis. ARD contains Level-2 products derived from Landsat Collections Level-1 scenes. ARD are tiled, georegistered, top of atmosphere, and...
What are LandsatLook images?
LandsatLook images are full-resolution .jpeg files that are included as options when downloading Landsat Collection 1 Level-1 data from EarthExplorer or GloVis. These are useful for simple visual interpretation without needing specialized software. Landsat Collection 2 LandsatLook images are now called "Full Resolution Browse images". Download them from EarthExplorer as individual files for each...
