The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are instruments onboard the Landsat 8 satellite, which was launched in February of 2013. The satellite collects images of the Earth with a 16-day repeat cycle, referenced to the Worldwide Reference System-2. The approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).
The spectral bands of the OLI sensor provide enhancement from prior Landsat instruments, with the addition of two spectral bands: a deep blue visible channel (band 1) specifically designed for water resources and coastal zone investigation, and a new infrared channel (band 9) for the detection of cirrus clouds. Two thermal bands (TIRS) capture data with a minimum of 100 meter resolution but are registered to and delivered with the 30-meter OLI data product. (See Landsat satellite band designations for more information.)
Landsat 8 Level 1 data products typically include data from both the OLI and TIRS sensor; however, there may be OLI-only and/or TIRS-only scenes in the USGS archive. The first two values of the Landsat 8 scene ID designates the data provided in each scene:
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. This file provides bit information regarding conditions that may affect the accuracy and usability of a given pixel – clouds, water or snow, for example.
Nearly 10,000 scenes were collected prior to the satellite achieving operational orbit, from launch to April 10, 2013. The earliest images are TIRS data only. These data are included in the Landsat 8 OLI/TIRS C1 Level-1 data set on EarthExplorer. While these data meet the quality standards and have the same geometric precision as data acquired after achieving operational orbit, the geographic extents of each scene will differ. Most of the scenes will process to full terrain correction, with a pixel size of 30 meters. There may be some differences in the spatial resolution of the early TIRS images due to telescope temperature changes.

Landsat 8 OLI/TIRS Collection 1
Landsat Tiers are the inventory structure for Landsat Collection 1 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. During Collection 1 reprocessing, all Landsat 8 OLI/TIRS scenes in the USGS archive are assigned to a specific “Tier”. 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 Precision Terrain (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 Systematic (L1GS) scenes. Users interested in Tier 2 scenes can evaluate the L1TP RMSE and other properties to determine suitability for use in their applications and studies.
- Real-Time (RT) – 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, these scenes are reprocessed, assigned to the appropriate Tier 1 or Tier 2 category, and removed from the RT Tier (Temporary designation).

Landsat—Earth observation satellites
Since 1972, Landsat satellites have continuously acquired space-based images of the Earth’s land surface, providing data that serve as valuable resources for land use/land change research. The data are useful to a number of applications including forestry, agriculture, geology, regional planning, and education.
