This research has been carried out to develop a method for effective using of the images of ERS-1, which has been launched in February 1992 in Japan. An experiment of lineament extraction from four pairs of stereoscopic images with different B/H ratio (0.1, 0.3, 0.5 and 1.0) has been executed at two kinds of areas-steep slope area and gentle slope area. The results of this experiment show that the most suitable B/H ratio for lineament extraction is different according to the steepness of the slope of test areas. 0.5 is the best B/H ratio at steep slope area (Izu peninsula), while 1.0 is the best at gentle slope area (Hishikari district) . Based on the results of this experiment, a new image analysis method has been developed. In this method, images are at first changed into stereoscopic images with the most suitable B/H ratio at the area, and then overlaid and displayed on a 3D display. Many useful informations can be extracted from these overlaid stereoscopic images.
