The panchromatic band 8 has a resolution of 15 meters.
Landsat 7 etm satellite images.
The landsat 7 etm instrument is designed with the significant exception of the thermal infrared band where the ground resolution has been improved from 120 to 60 m.
The observation bands are essentially the same seven bands as tm and the newly added panchromatic band 8 with a high resolution of 15m was added.
This gallery includes all landsat images published on the earth observatory visible earth and landsat science web sites from all seven landsat satellites landsats 1 8 landsat 6 failed to achieve orbit.
The etm instrument incorporates a new 15 m panchromatic band as well as a 9 bit analog to digital converter.
Landsat 7 etm images consist of eight spectral bands with a spatial resolution of 30 meters for bands 1 to 7.
The 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.
All of the images are in the public domain and may be used with attribution.
