Paper Abstract

Imaging spectrometry (also known as "hyperspectal imagery", HSI) data are well established for detailed mineral mapping from airborne and satellite systems. Overhead data, however, have substantial additional potential when used together with ground-based HSI measurements. An HSI scanner system was used to acquire airborne data, outcrop scans, and to image boxed drill core and rock chips at approximately 6nm nominal spectral resolution in 360 channels from 0.4 - 2.45 micrometers. Analysis results using standardized hyperspectral methodologies demonstrate rapid extraction of representative mineral spectra and mapping of mineral distributions and abundances. A case history highlights the capabilities of these integrated datasets for developing improved understanding of relations between geology, alteration, and spectral signatures in three dimensions.
