In this study, in order to explain the characteristics of topography in Akkeshi town, examination on effective application of digital maps in an open class was done. A bird's-eye view of Akkeshi town is a good tool to show the development of rocky coasts and marine terraces and also to show the channel patterns of Bekanbeushi river and Oboro river. A cross section is helpful in explaining the difference between the typical shape of stream valleys which are formed in hard rock area and the typical one formed in comparatively soft rock area. On the other hand, a longitudinal section of each river is suitable for the beginners who try to understand the mechanism of sediment transport in a river. Using digital maps, a lecturer can draw easily the figures described above.
