Thematic Mapper (TM) Overview
Instrument Design
Carried on board Landsat-4 and 5 satellites, the Thematic Mapper (TM) was a whiskbroom instrument designed and built by SBRC (Santa Barbara Research Centre) of Hughes Aircraft Company in Goleta, USA.
The instrument was regarded as a second generation imager for monitoring Earth's resources with considerably improved spectral and spatial resolutions over those of the Multi Spectral Scanner (MSS) which was used onboard the Landsat-1 to 5 satellites.
The TM instrument was a multispectral scanning radiometer operating in the visible and Infra-Red regions of the Electromagnetic Spectrum that was carried on board Landsat-4 and 5.
