CEOS Instrument: Thematic Mapper

Agencies: USGS [Primary]
Missions: Landsat-4
Type:High resolution optical imager
Description:Measures surface radiance and emittance, lands cover state and change (eg vegetation type). Used as multipurpose imagery for land applications
Spatial Resolution: VIS - SWIR, 30 m; TIR: 120 m
Swath Width: 185 km
Wavebands: VIS - TIR: 7 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.
