Geothermal is the cheapest resources given to human being by the earth. The best way of its regional investigation is thermal inferred remote sensing. Thermal inferred image is a precise distributive mapping of the temperature of all earth's surface, which generally reflects clearly the geothermal body directly exposed to the earth's surface. By means of the image processing of Taian suburb TM image, especially band 6, the information of geothermal resource is taken up. Combining geophysical method and survey temperature onsite, the geothermal range is enclosed. On basic of these above, the author investigates the geology of the earth's surface and analyses the underground water, put forward the mechanism of the geothermal formation in the area, conduced a set of RS ways of geothermal resource investigation.
