This map, in ERDAS Imagine (.img) format, has been attributed by pixel value with material identification data that can be queried in most image processing and GIS software packages. Purpose: The purpose of the image is to display iron-bearing minerals and water detected using low-altitude AVIRIS data over the White Horse replacement alunite deposit.

The digital number (DN) values in this image have been attributed by material identified through spectroscopic analysis of low-altitude AVIRIS data as shown in the following table. Each DN value corresponds to a particular color in the included color table. All pixels identified as a particular material have been assigned a single, discrete color. Certain materials have had a continuous (or gradational) stretch applied in which the brightness of that color for a particular pixel value is indicative of the fit x depth values derived from spectroscopic analysis, with bright shades of color indicating high fit x depth, and successively darker shades indicate lower fit x depth values. Fit x depth is proportional to both the degree of least-squares fit between reference and image spectra, and depth is proportional to material abundance given a constant grain size. Pixels in which no material was identified have no material identification attribute, and these pixels are represented in the color table with a gray scale color (red = green = blue), and can either be displayed to show a gray scale background of a single AVIRIS band, or turned off (for example using ArcMap unique value symbology properties) so that only pixels in which material was identified are shown.
