Landsat is more than just a camera with a great zoom lens orbiting Earth. Landsat measures light reflected by Earth from the sun. The light that Landsat measures reveals a lot about the earth’s surface, since different surfaces reflect various types of light. In the Tour of the Electromagnetic Spectrum you can learn about the types of light that exist and through Landsat More Than a Pretty Picture (PDF) you can discover the types of light that Landsat measures to create a number of useful images. These images reveal more about Earth than meets the eye. Once you’ve learned how Landsat works, make your own Landsat image and experiment with different combinations of light.
