Landsat

 officially Earth Resources Technology Satellites

Any of a series of unmanned U.S. scientific satellites. The first three were launched in 1972, 1975, and 1978. They were designed mainly to collect information about Earth's natural resources. They were also equipped to monitor atmospheric and oceanic conditions and to detect variations in pollution levels and other ecological changes. Three more Landsat satellites were launched successfully, in 1982, 1984, and 1999; radio communication with Landsat 6 was lost immediately after its launch in 1993.

Landsat 5 TM (Thematic Mapper) sensor has many advantages in ecological applications (Cohen & Goward, 2004) because of its suitable spatial resolution (grain size associated with the grain of land management), spectral resolution (all major portions of the solar electromagnetic spectrum are represented), and temporal resolution (systematically collected remote sensing data over more than 30 years).
