Field checking of vegetation and mineral maps produced from the 1996 AVIRIS data was conducted in late September and early October 1998 by Ray Kokaly and Eric Livo. Spot checking of minerals and vegetation cover types was conducted in areas near Norris Geyser Basin and Mammoth Hot Springs.
Examples of Field Checking:
Photos from field checking of pixels that mapped as vigorous
lodgepole pine regrowth from the 1988 fires. These photos
show very dense regrowth, some taller than 2 meters. In the
AVIRIS data this area had stronger chlorophyll and water
absorptions than the majority of lodgepole regrowth.
