Abstract :
The thermal infrared band of the Landsat can reflect land surface temperature difference, so the ETM+ data is chosen to explore underground heat water. Through temperature retrieval, grey stretch, band combination and so on, the image processing method of stressing underground heat water distribution information is decided. The experiment result shows the best result is the band combination of the grey stretch of band6 - band7, band5 and band3. In order to stress the underground heat water further, the image fusion is carried out by using IHS transformation and wavelet transformation to achieve better underground heat water distribution map.
