The images of different Kinds can be obtained by using different methods in processing satelaite data. The images of Liaohe basin, produced by a combined processing method that is linear stretch -histogram adjust-local entrance-colors, are very effective in understanding the relief and structural features of pre-Tertiary base of the area. The geological interpretation of the images confirms that the northeastern (including north-north-eastern) linear structures are dominant in the basin. However, the remote sensing data show the effect of the northwestern linear structures on the formation of the basin. The geological interpretation also reveals that the ring image of the basin has two remarkable featuers. 1). the light tone mainly represents positive structures; 2). the dark tone mainly represents negative structures. Because the known oilfields have bright light tone ring or lump shape, if additional geological data are also Syntheticalay analyzed, new oilfields can be Predicted by the method of analogy.
