Airborne Visible/Infrared Imaging Spectrometer 
(AVIRIS) data. The expert system has successfully 
identified the minerals kaolinite, alunite, and 
buddingtonite at one site using 64 channel imaging 
spectrometer data and the minerals hematite, 
goethite, sericite (fine grained muscovite), calcite and 
dolomite at another site using the 224 channel 
AVIRIS data. 
The efficient use of automated techniques 
simplifies the task of extracting information from 
imaging spectrometer data and brings within reach 
analysis of data sets such as AVIRIS and HIRIS. It 
now appears as if we will have an operational expert 
system for analysis of imaging spectrometer data 
well before the launch of EOS. This system should 
make it possible for investigators to concentrate on 
basic science research rather than data reduction.

This research was partially funded by NASA 
under grant NAGW-1601. Additional support for 
analysis of AVIRIS data was provided under NASA 
grant NAGW-1143.
