The exploitation of geothermal resource has very important significance to make the best use of clean energy sources, play down the strain in energy sources and develop circulatory economy. At present, the traditional geophysical exploration method of geothermal resource has the disadvantages of long period and large investment resulted by the anomalies in gravity, magnetism and electricity. It is likely to appear large risk investment or blind mining. However, the exploitation of geothermal resource based on modern remote sensing technique that uses infrared wave band has the characteristics of speediness, large area and lower cost in geothermal information extraction. Using relative data processing method, we carried through remote sensing geological interpretation. According to the differences of ground object radiation temperature reflected by earth satellite infrared remote sensing data, we enhanced effects in band difference algorithm and HIS (HLS) color switch in order to distill the distribution of geothermal anomaly. Finally, based on an information pattern, we got the geothermal area through combining remote sensing geological interpretation with information in geological structure and landform, and directed the searching of geothermal water in unknown region. This technique is scientific, valid, and ought to be applied in other regions.
