Instrument Technology Overview
The Earth Observing-1 (EO-1) mission is flying three
advanced technology verification land imaging instruments.
They are the first Earth-observing instruments to be
flown under NASAs New Millennium Program. The
three instruments are the Advanced Land Imager (ALI),
the Hyperion hyperspectral imager, and the Linear Etalon
Imaging Spectrometer Array (LEISA) Atmospheric Corrector
(LAC). These instruments incorporate revolutionary land
imaging technologies that will enable future Landsat
and Earth observing missions to more accurately classify
and map land utilization globally.
