USGS EROS Archive - Landsat Archives - Landsat 8-9 Operational Land Imager and Thermal Infrared Sensor Collection 2 Level-1 Data
Landsat 8-9 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) Collection 2 Level-1 15- to 30-meter multispectral data.
The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are onboard the Landsat 8 satellite and have acquired images of the Earth since February 11, 2013. Copies of the same instruments are onboard the Landsat 9 satellite, which was launched September 27, 2021. The OLI and TIRS on each satellite collect images of the Earth with a 16-day repeat cycle, referenced to the Worldwide Reference System-2. Together, the satellites have an 8-day acquisition offset. The approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).
Delivered Landsat 8-9 Level-1 products consist of 11 spectral bands with a spatial resolution of 30 meters for bands 1-7 and bands 9-11, and 15-meters for the panchromatic band 8. (See Landsat satellite band designations for more information.) Each Level-1 product typically include both OLI and TIRS data; however, there may be times when one of the sensors cannot acquire data; the first two values of the Landsat Product Identifier designates the data contained in each scene: (Landsat 8 used as examples)
- LC08_L1TP_003055_20170207_20170216_01_T1 = Combined (both OLI and TIRS data)
- LO08_L1TP_021047_20150304_20170227_01_T1 = OLI data only
- LT08_L1GT_137206_20170202_20170215_01_T2 = TIRS data only
A Quality Assurance (QA.tif) band is also included in the Level-1 product. This file provides bit information regarding conditions that may affect the accuracy and usability of a given pixel – clouds, water, or snow, for example.

Landsat 8-9 OLI/TIRS Collection 2 Level-1 Data
Landsat Tiers are the inventory structure for Landsat Collection Level-1 data products and are based on data quality and level of processing. All scenes in the Landsat archive are assigned to a Collection category. The purpose of Collection categories is to support rapid and easy identification of suitable scenes for time-series pixel level analysis. These data have well-characterized radiometric quality and are cross-calibrated among the different Landsat sensors.
Collection Category (Tier)
- Tier 1 (T1) – Contains the highest quality Level-1 Terrain Precision (L1TP) data considered suitable for time-series analysis. The georegistration is consistent and within prescribed tolerances [<12m root mean square error (RMSE)].
- Tier 2 (T2) – Contains L1TP scenes not meeting Tier 1 criteria and all Systematic Terrain (L1GT) and Geometric Systematic (L1GS) scenes. Users interested in Tier 2 scenes can evaluate the RMSE and other properties to determine suitability for use in their applications and studies.
- Real-Time (RT) (Landsat 8 only) – Contains newly acquired Landsat 8 scenes, which require a period of evaluation and calibration adjustment after acquisition but are processed immediately based on preliminary calibration coefficients, assigned to the temporary RT Tier, and made available for download. When definitive calibration information becomes available (approximately 14-16 days), these scenes are reprocessed, assigned to the appropriate Tier 1 or Tier 2 category, and removed from the RT Tier.
Visit the Landsat Levels of Processing webpage to learn more about how georegistration is applied to Landsat Level-1 products.
