This image consists of six bands (bands 1-4, 6, and 8) of an ASTER dataset covering the study area. These data have been georeferenced to the Universal Transverse Mercator projection using a projective transform with ground control points and a digital elevation model from the USGS National Elevation Dataset (1/3 arc second, 10m resolution). The data have been edge enhanced to improve clarity. This image, in ERDAS Imagine (.img) format, has been designed for viewing and integration with other geospatial data in most image processing and GIS software packages. Purpose: The purpose of the image is to enable multispectral display of the ASTER data over the White Horse replacement alunite deposit and surrounding area, including the Tushar Mountains, Pahvant Range, and Sevier Plateau. The image file can be used to display color composites (band assignments to red, green, and blue colors) that are useful for visual discrimination of surface features. 431/RGB color composite (Fig. 10): visualization of vegetation communities and densities, soil albedo (affected by moisture content which will absorb infrared light, resulting in a bluish tint for moist soils, soil type, and mineral type), snow, and rock type. Similar in appearance to Landsat Thematic Mapper (TM) 542/RGB composite. 321/RGB color composite: visualization of vegetation (shown in hues of red, with higher areal chlorophyll contents in brighter red usually corresponding to higher densities of green vegetation) and ferric iron content of rocks and soils (undisturbed, moderate-albedo surfaces with high ferric iron content will appear in hues of yellow to greenish yellow; high-albedo surfaces such as playas, mine dumps, tailings, and areas of un-mined and weathered pyritic rocks such as Big Rock Candy Mountain will appear white to light cyan). Similar in appearance to Landsat TM 432/RGB composite. 468/RGB color composite (456/RGB for this dataset): visualization of rock and mineral type. Magenta: minerals with Al-OH SWIR absorptions (clays, sulfates, and white micas). Red: Al-OH minerals + ferric iron +/- minor carbonate +/- dry vegetation. Orange to reddish orange: dry vegetation +/- minor Al-OH minerals +/- minor carbonate. Brown to reddish brown: green vegetation. Yellow/Green: carbonate minerals (e.g. calcite, dolomite) more likely yellowish; chlorite, epidote and(or) amphiboles with ferric/ferrous iron absorptions more likely greenish.

Prior to edge enhancement, data have been converted to radiance units (W/m2/sr/micron) through multiplication by gain values per band. Although the SWIR data (bands 4-9) have a GIFOV of 30m, they have been resampled to 15m pixel size to match that of the VIS-NIR data (bands 1-3). Each of the six included ASTER bands has attributes generated by the author using ERDAS software regarding edge-enhanced radiance values, value histogram frequency counts, contrast table data, and contrast table breakpoints for the contrast stretch. Contrast stretches are only applied to the data if they are loaded in ERDAS Software. All attributes are accompanied by statistics of data distributions.
