Electromagnetic spectrum

Landsat is a joint mission of NASA and the U.S. Geological Survey (USGS) and is a part of the National Land Imaging (NLI) Program.

The Landsat glossary defines electromagnetic spectrum as: “The entire range of radiant energies or wave frequencies from the longest to the shortest wavelengths--the categorisation of solar radiation. Satellite sensors collect this energy, but what the detectors capture is only a small portion of the entire electromagnetic spectrum. The spectrum is usually divided into seven sections: radio, microwave, infrared, visible, ultraviolet, x-ray and gamma ray radiation”.
