The Landsat Data Continuity Mission (LDCM) is the future of Landsat satellites. LDCM launched on February 11, 2013. Landsat satellites view the Earth through a number of different bands. Each band captures imagery in different spectral wavelengths. Scientists can combine these bands a number of ways to obtain information about the satellite imagery. This visualization shows several different band combinations over the Florida Everglades.
