Abstract

Geophysical Environmental Research (GER) 63-channel aircraft scanner data were used to map the mineralogy at Makhtesh Ramon in the Negev area of southern Israel. The data were calibrated to apparent reflectance using three techniques: the flat field (FF) method, the empirical line (EL) method, and the internal average relative reflectance (IARR) method. Results of these calibrations were evaluated by extracting image spectra and comparing them to library spectra for pure minerals and to laboratory spectra of samples collected from the field area. -from Authors
