Landsat Missions
Question:
What are the band designations for the Landsat satellites?
Answer:
Landsat Multispectral Scanner (MSS) images consist of four spectral bands with 80 meter spatial resolution. Approximate scene size is 170 km north-south by 185 km east-west (106 mi by 115 mi). Specific band designations differ from Landsat 1-3 to Landsat 4-5.
| Multispectral Scanner (MSS) |
Landsat 1-3 |
Landsat 4-5 |
Wavelength (micrometers) |
Resolution (meters) |
| Band 4 | Band 1 | 0.5-0.6 | 80 | |
| Band 5 | Band 2 | 0.6-0.7 | 80 | |
| Band 6 | Band 3 | 0.7-0.8 | 80 | |
| Band 7 | Band 4 | 0.8-1.1 | 80 |
Landsat Thematic Mapper (TM) images consist of seven spectral bands with a spatial resolution of 30 meters for bands 1 to 5 and 7. Spatial resolution for band 6 (thermal infrared) is 120 meters, but is resampled to 30-meter pixels. Approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).

| Band 1 | 0.45-0.52 | 30 | |
| Band 2 | 0.52-0.60 | 30 | |
| Band 3 | 0.63-0.69 | 30 | |
| Band 4 | 0.76-0.90 | 30 | |
| Band 5 | 1.55-1.75 | 30 | |
| Band 6 | 10.40-12.50 | 120* | |
| Band 7 | 2.08-2.35 | 30 |
* TM band 6 was acquired at 120-meter resolution, but the delivered product is resampled to 60 meter pixels.
Landsat Enhanced Thematic Mapper Plus (ETM+) images consist of eight spectral bands with a spatial resolution of 30 meters for bands 1 to 5 and 7. Resolution for band 6 (thermal infrared) is 60 meters and resolution for band 8 (panchromatic) is 15 meters. All bands can collect one of two gain settings (high or low) for increased radiometric sensitivity and dynamic range, while band 6 collects both high and low gain for all scenes. Approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).

Data collected for the LDCM Mission by the Operational Land Imager (OLI) instrument will consist of the nine bands. By collecting land-surface data with spatial resolution and spectral band specifications consistent with historical Landsat data, the OLI instrument will advance future measurement capabilities, with an ultra-blue band (band 1) for coastal and aerosol studies, as well as band 9, which will be useful for cirrus cloud detection. At this time, no thermal bands will be included on this mission. Scene size will be comparable to current Landsat scenes.
