Abstract
<p>Mineral spectra of rocks and minerals have been widely measured and published through the internet, for example, by U.S. Geological Survey (USGS) and Geological Survey of Japan (GSJ). Among them, transition metal oxide minerals such as hematite and goethite and hydro-oxide minerals such as clays and sulfates are good targets to identify for geologic mapping through the spectral analysis of satellite images. The identified results can be analyzed by QGIS processing with comprehensive expressions as GIS layers.</p>
