| Definition | The TM (Thematic Mapper) is a whick broom passive optical imager designed to measure Earth's surface reflectance in seven spectral bands for high-resolution land and vegetation observation. It is a follow-on instrument to the MSS (Multispectral Scanner System). TM provides information on the Earth's surface in the visible, near, middle and thermal infrared regions of the electromagnetic spectrum. IT does this using a mirror which scans across the satellite's ground track, reflecting light into a single detector which collects data one pixel at a time. The seven spectral bands range in wavelength from 0.45-0.52 micrometres (band1); 0.53-0.61 micrometres (band 2); 0.63-0.69 micrometres (band 3); 0.78-0.90 micrometres (band 4); 1.55-1.75 micrometres (band 5); 10.4-12.5 micrometres (band 6); 2.09-2.35 micrometres (band 7). All bands have a 30 m resolution except band 6 which has a 120 m resolution. Flown on Landsat-4, Landsat-5. http://wiki.landscapetoolbox.org/doku.php/remote_sensor_types:landsat_tm_5#description |
