562 Figure 3 a and b). For the atmospherically corrected high spectral resolution FLI data, first derivative calculations over the red edge region (0.68 to 0.80 microns) can be performed. The extended spectral range of the AVIRIS sensor allows a study of the NIR region of the spectrum. Some problems were encountered with the processing of both AVIRIS and FLI data. If raw 224 spectral channel AVIRIS data is used, overlapping spectral channels from different spectrometers must be masked in the software using a user input channel masking vector. The data is converted to reflectance during the calibration stage using ground truth data. Each image is calibrated in reflectance units using a different calibration file and required a slightly different channel masking vector. The current approach easily allowed different calibration files and masking vectors to be used for each image but a more efficient solution would be to store these in an image header record lessening the chance of a mix-up in calibration files. CONCLUSIONS The current emphasis has been on a flexible, expandable software environment, which allows an analyst to interact with the data set, displaying reflectance spectra and defining interpretation algorithms. This feature is considered important because of the difficulty of assessing an optimum approach to dealing with hyperspectral imagery. In the future we plan to incorporate new interpretation algorithms suited to imaging spectrometery data and remote sensing applications. REFERENCES Freemantle, J. R. and Miller J. R., 1987.
