Landsat 5 image showing the Seattle area

Example of the Landsat 4-5 TM Collection 2 level-1 product. This Landsat 5 image was acquired on October 6, 2010 near Seattle, Washington and is shown as a natural color composite using the red, green, and blue bands (bands 3,2,1).

(Public domain.)

The Landsat Thematic Mapper (TM) sensor was carried onboard Landsats 4 and 5 from July 1982 to May 2012 with a 16-day repeat cycle, referenced to the Worldwide Reference System-2. Very few images were acquired from November 2011 to May 2012. The satellite began decommissioning activities in January 2013.

Landsat 4-5 TM image data files consist of seven spectral bands (See band designations). The resolution is 30 meters for bands 1 to 7.  (Thermal infrared band 6 was collected at 120 meters but was resampled to 30 meters.) The approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).

Product Processing Parameters

Most Landsat 4-5 TM Collection 2 Level-1 data are process through the Landsat Product Generation System (LPGS), processed to full Precision Terrain corrections with the following parameters:

Parameter  
Pixel Size 30 meters
Output Format Cloud Optimized GeoTIFF (COG)
Resampling Method Cubic Convolution (CC)
Map Projection UTM – WGS 84 Polar Stereographic for the continent of Antarctica.
Image Orientation Map (North Up)
Distribution HTTPS Download Only
Delivery Time Immediate download

While most Landsat 4-5 TM scenes are processed to full Terrain Precision Correction (L1TP), some scenes do not have the ground-control or elevation data necessary to perform these corrections. In the cases, the best level of correction is applied. See Landsat Processing Details for details on correction levels.

Specific terrain precision corrected scenes are available for most of the globe under the Global Land Surveys (GLS) collections of 1975, 1990, 2000, 2005, and 2010. These datasets can be found on EarthExplorer or the USGS Global Visualization Viewer (GloVis)

Some TM scenes were processed using the National Land Archive Production System (NLAPS). These scenes are not included in Landsat Collection 2.

Landsat 4-5 TM Collection 2 Level-1 Data

Landsat Tiers are the inventory structure for Landsat Collection 2 Level-1 data 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 2 Categories

  • 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.

The Landsat Collections page contains additional information about changes applied to Landsat Level-1 data for Collection 2.

Additional Information

Access Data

Landsat 4-5 Thematic Mapper (TM) Collection 2 Level-1 scenes held in the USGS archive can be searched using EarthExplorer.  On EarthExplorer, Landsat 4-5 TM scenes can be found under the Landsat menu in the “Landsat Collection 2 Level-1” section, in the “Landsat 4-5 TM C2 L1” dataset.

Some Landsat 5 TM scenes outside the United States were collected and archived at International Ground Stations.  The Landsat Global Archive Consolidation (LGAC) effort continues to bring this data back to the USGS archive.
