ASTER on NASA’s Terra Platform • The 1 st (and only…) geoscience-tuned satellite sensor

ASTER on NASA’s Terra Platform • The 1 st (and only…) geoscience-tuned satellite sensor • Launched in 1999 on Terra Platform • Joint project of U. S. NASA and Japan Ministry of Economy, Trade, and Industry • Wide Spectral Coverage - 14 bands in VNIR, SWIR, TIR • High Spatial Resolution - 15 m to 90 m • Along-Track Stereo Capability • 60 km Swath Width • Systematic global coverage • SWIR module failed in 2009 CA-06 Energy and Mineral Resources Management GEO-XIII Plenary St. Petersburg 8 November 2016
