Abstract :
The Hyperion instrument was launched on November 21, 2000 mounted on the EO-1 spacecraft into an orbit 1 minute behind Landsat 7. Hyperion has a 7.5 km swath width, a 30 metre ground resolution and more than 220 spectral bands. Part of the on-orbit characterization involves MTF measurements from several ground scenes. These scenes included edges from the Moon and glaciers as well as several bridges. The scenes were processed to determine the MTF for both the VNIR and SWIR imaging spectrometers and were compared to measurements made prior to launch
