Outline of Final Research Achievements

Topographic anaglyph images were viewed with red-cyan glasses enable to recognize topographic relief features easily. The aim of this study was to introduce topographic anaglyph images produced from detailed digital elevation model (DEM). The extensive area of anaglyph produced from detailed DEM is advantageous for identifying broad tectonic geomorphology near a coastal area, as well as in urban areas, to view ‘naked’ topography exaggerated vertically.
DEM have been indispensable data for identifying fault traces and measuring the amount of recent active faulting. However, some of the DEM produced by Air-boned / Terrestrial LiDar are difficult to observe the tectonic geomorphology because of artificial modification, or because its density is too sparse. In this study, we attempt to construct DSM by using SfM (Structure from Motion) - MVS (Multi-View Stereo) with old aerial photographs as well as Hi-view photographs by a compact digital camera.
