Abstract

The SWIR full spectrum imager (SFSI), an imaging spectrometer covering the short-wave IR (SWIR) from 1220 to 2420 nm, has been developed at the Canada Centre for Remote Sensing for use on an airborne platform. The sensor has ben designed to acquire simultaneously a full spectrum resolution and a full image swath at high spatial resolution. The sensor was test flown in Nevada in June 1995. Data from this mission are analyzed on the Imaging Spectrometer Data Analysis System. A look-up-table driven atmospheric correction procedure is used to retrieve surface reflectances. An image cube of a site near Virginia City is processed via spectral unmixing using reflectance spectra extracted from the image at ground sample sites and spectra of mineral samples acquired by a ground-based field spectrometer. The resulting end member abundance maps indicate that SFSI data can be analyzed successfully in this way for mineral identification.
