Outline of Final Research Achievements

High-resolution digital elevation model (DEM) has been rapidly developed, and thus expected to be applied to tectonic geomorphological study. We created various types of stereo-pair images based on the DEM. In addition, we developed a GIS-based mapping system that enabled us to 1) make interpretation-result map, and 2) measure amounts of tectonic movements. We improved the system many times, by applying the system to geomorphic studies on fault-related landforms and landslide features. We finally confirmed the usefulness of our developed mapping system. This is, for example, supported by success of 1) analysis of Holocene marine terraces in Kumano City, and 2) examination of surface-trace distribution of the ISTL active fault system.
