“While Landsat instruments are fundamentally just electrooptical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing.” —Aram Mika, 1997

Landsat spectral bands

Note: atmospheric transmission values for this graphic were calculated using MODTRAN for a summertime mid-latitude hazy atmosphere (circa 5 km visibility). Graphic created by L.Rocchio & J.Barsi.

To compare the exact band designations in tabular form, please visit the USGS page “What are the band designations for the Landsat satellites?”
