This paper introduced a method to extract the ground water information in loess hill drought area based on landsat ETM thermal infrared data.Based on the pre-processing for the data,such as geometric correction and data fusion,the principal component analysis and best density separation for images were disposed,and the information of groundwater was extracted effectively.With the data analysis and field investigation,the accuracy of the results was validated,which supplies the technique and method for searching the ground water resources fast and efficiently.
