The Landsat Thematic Mapper (TM) on Landsat 4 and Landsat 5 measured visible, near-infrared, and shortwave infrared light, along with thermal (heat) infrared radiation. The TM had an improved spatial resolution of 30 meters and sharper spectral separation and greater radiometric accuracy and resolution than the Multispectral Scanner (MSS).
