CEOS Instrument: Enhanced Thematic Mapper Plus




Instrument:ETM+
Agencies: USGS [Primary]
 NASA
Mission: Landsat-7
Status:Operational
Type:High resolution optical imager
Description:Measures surface radiance and emittance, land cover state and change (eg vegetation type). Used as multi-purpose imagery for land applications
Spatial Resolution: PAN: 15 m, VIS - SWIR: 30 m, TIR: 60 m
Swath Width: 185 km
Wavebands: VIS - TIR: 8 bands: 0.45 - 12.5 ?m
Technology: High resolution optical imager
Description: Imaging Vis/IR radiometer whose characteristics are stressed towards spatial resolution (typically <30 m). Spectral coverage in bands of Vis and NIR (0.4-1.3 Ám). Number of channels can be small (extreme: one, i.e. panchromatic) or very large (hyperspectral) separated in-field (array detectors) or by a spectrometer, or a combination of both. Channel bandwidths from 0.5 Ám (PAN) to 5 nm (hyperspectral). Applicable only in LEO.
