| Overview |
|
Landsat (name indicating Land + Satellite) imagery is available since 1972 from six satellites in the Landsat series.
These satellites have been a major component of NASA's Earth observation program, with three primary sensors evolving over thirty
years: MSS (Multi-spectral Scanner), TM (Thematic Mapper), and ETM+ (Enhanced Thematic Mapper Plus). Landsat supplies high resolution
visible and infrared imagery, with thermal imagery and a panchromatic image also available from the ETM+ sensor.
The collection of Landsat available through GLCF is designed to compliment overall project goals of distributing a global, multi-temporal,
multi-spectral and multi-resolution range of imagery appropriate for land cover analysis.
