SPECTRAL REFLECTANCE OF GEOTHERMAL AREA SURFACE AS FUNCTION OF ELECTROMAGNETIC WAVELENGTH WITH LANDSAT THEMATIC MAPPER

Abstract

Research in the field of geothermal energy that utilize remote sensing techniques specifically examine how the spectral characteristics of each parameter surface geothermal area, and determine the appropriate wavelength sensing to identify potential geothermal areas, is still lacking. This study aims to determine the spectral reflectance surface geothermal area as a function of electromagnetic wavelengths, using Landsat Thematic Mapper reflective channel. For this purpose, this study used a single channel digital analysis method Landsat TM remote sensing for the acquisition of surface reflectance values geothermal area. The test results indicate that not all single-channel Landsat TM can distinguish regional and local manifestations are not manifest. Thus, the area's geothermal potential is characterized by the of manifestations at the surface, and a generally closed vegetation, can be identified based on sensing the wavelength of green and near infrared.
