The application of national numerical information to Landsat data processing has been proposed. The digital terrain data (KS-110) have been employed to make a stereo pair of Landsat images, while a shaded relief image and a stereo pair of shaded relief images have been also made from KS-110 in the preliminary stage of processing. The shaded relief images have following advantages compared with Landsat images; (i) easy production of the image which covers extensive area, (ii) free choice of direction of the Sun light and of eyes, (iii) no interruption of the clouds, while they have worse resolution than Landsat images. Therefore, they are valuable not only because of the assistance for Landsat image analysis, but also valuable, in themselves, as an expression of topography. A stereo pair of Landsat images is a very useful tool for geological interpretation nevertheless some technical problems; for example, deterioration of image quality, remain in the present study. However, these problems are not essential, the value of the stereo pair of images will be increasing especially when the resolution of the digital terrain data will be finer.
