Abstract
This report documents part of a cooperative study by CFE and UURI of a Landsat 5 image of the Los Azurfres geothermal area and its surroundings. The objective was to determine if processing and interpretation of satellite imagery are useful in volcanic environments for mapping structures, hydrothermal alteration, rock types and/or soil geochemical anomalies manifest in vegetation. Several processing steps were carried out using the ERDAS image processing system installed on an AT equivalent PC at UURi in an attempt to detect characteristic signatures form hydrothermally altered areas to enhance linear and other structurally related geological features.
