The Enhanced Thematic Mapper Plus (ETM+) instrument is a fixed 'whisk-broom', eight-band, multispectral scanning radiometer capable of providing high-resolution imaging information of the Earth's surface onboard Landsat 7. The main improvement from the Landsat 4/5 Thematic Mappers (TMs) is the addition of a panchromatic band with 15 m spatial resolution.
Spectral and spatial characteristics of these bands are shown below.

Band no. 1
Spectral range .450 to .515 micrometres Ground resolution: 30 m
Band no. 2
Spectral range .525 to .605 micrometres Ground resolution: 30 m
Band no. 3
Spectral range .630 to .690 micrometres Ground resolution: 30 m
Band no. 4
Spectral range .775 to .900 micrometres Ground resolution: 30 m
Band no. 5
Spectral range 1.550 to 1.750 micrometres Ground resolution: 30 m
Band no. 6
Spectral range 10.40 to 12.50 micrometres Ground resolution: 60 m
Band no. 7
Spectral range 2.090 to 2.35 micrometres Ground resolution: 30 m
Band no. 8
Spectral range .520 to .900 micrometres Ground resolution: 15 m
