The accurate delineation of geothermal resources with remote sensing technology is one hot topic in recent years. Remote sensing images used in previous studies, are mostly space multi-spectral remote sensing images, spectral resolution and spatial resolution are relatively low, difficult to accurately delineate the geothermal anomaly. Considering those research at home and abroad, using Hyperspectral resolution remote sensing images, choosing Lintong area for the study area. Because of hyperspectral remote sensing images exist in the acquisition process more obvious geometric distortion, during data processing, information extraction, geothermal anomaly delineated and so the information is needed before the image is first geometrically corrected in order to obtain high precision and high-quality remote sensing images. This research in this regard a useful exploration and obtained ideal result.
