The file sizes of Landsat Collection 1 Level-1 data products are listed below:
| Sensor | Compressed file |
Uncompressed file |
|---|---|---|
| Landsat 8 OLI/TIRS | 919 MB | 1.61 GB |
| Landsat 7 ETM+ | 235 MB | 785 MB |
| Landsat 4-5 TM | 150 MB | 500 MB |
| Landsat 1-5 MSS | 20 MB | 75 MB |
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...
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...
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.

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...
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...
LandsatLook images were full-resolution JPEG files that were included as options when downloading Landsat Collection 1 Level-1 data from the USGS. In 2020, these files were renamed Landsat Collection 2 Full Resolution Browse images. These images, useful for simple visual interpretation without needing specialized software, can be downloaded from EarthExplorer or GloVis. Learn more: Collection 2...

This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors.
