We are accomplishing the above goals using diagnostic spectral features
to identify specific molecular absorption bands in the spectra of
surficial materials. Currently, we are using the NASA Airborne Visual
and Infra-Red Imaging Spectrometer (AVIRIS) system for our mapping.
AVIRIS produces approximately 17-meter ground spatial resolution (pixel
to pixel spacing) in an image 614 pixels (10.5 km) wide and many
kilometers long. The spectra cover the 0.4 to 2.5 micron spectral
range in 224 bands at 0.01-micron spacing. This spectral resolution
allows us to resolve
absorption bands due to
specific chemical bonds in materials.
Every pixel in the image has such a spectrum, so we are able
to spatially map the presence and abundance of those bonds as seen from
the aircraft. The chemical bonds are associated with specific
materials, whether solid, liquid, or gas. Thus, we can produce
maps of specific materials.

and many examples of what can be done with
