Landsat satellites have been acquiring imagery of the earth since 1972 and are the most successful and longest running series of earth-viewing satellites. The most recent, Landsat 8, was launched on February 11, 2013.

Initially equipped with the Multispectral Scanner (MSS), Landsat satellites began carrying the much improved TM instrument in 1982. TM and ETM+ collect data in 6 spectral bands at 30-meter spatial resolution. The TM has an additional 120-meter thermal band while the ETM+ has an enhanced 60-meter thermal band. The ETM+ also has a 15-meter panchromatic band.

Beginning with Landsat 8, the satellite now carries two push-broom sensors: the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS), both of which provide 12-bit radiometric quantization of the data (previous Landsat data is 8-bit). The OLI collects data in nine shortwave bands—eight spectral bands at 30-meter resolution and one panchromatic band at 15 meters. The TIRS captures data in two long wave thermal bands with 100-meter resolution, and is registered to and delivered with the OLI data as a single product. TIRS data products have a 30-meter resolution. Landsat data are used in a wide variety of applications in Kansas.
