Geologic Remote Sensing in the Thermal Infrared

摘要

Remote sensing of emitted radiance form the Earth's surface in the thermal infrared region (8 to13is useful for geologic studies including lithology and soil and mineral mapping. Since 1982, new airborne, field portable and spaceborne instruments have been demonstrating the advantages of multispectral measurements in this region for geologic applications. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), presently being built in Japan is the newest of the spaceborne multispectral instruments.
