• Anaglyph Images of Japan Produced from Digital Elevation Model : Explanatory Text and Sheet Maps

抄録

Anaglyph images and red-cyan glasses enable us to easily observe topographic relief, including seafloor. We have stored detailed digital elevation model (DEM) data published by Geospatial Information Authority of Japan (GSI) since the Basic Act on Promotion of Utilization of Geographical Information was started in 2007. In this paper, we present anaglyph images produced from 10-m-mesh DEM of GSI throughout all territory of Japan, as well as anaglyph images from 5-m-mesh DEM for large alluvial plains of Japan. We also describe a method for producing stereo-pair image not only from DEM but also from contour lines. In anaglyph images, we can identify active faults that have deformed alluvial plains, terrace surfaces, and seafloors. Smaller fault scarps and fault-related broad deformations can be newly identified in numerous sites on land as well as on seafloor by means of interpreting anaglyph images. For example, we report tectonic geomorphology on the shallow seafloor in the northern offing of Noto peninsula. This paper and Goto and Sugito (2012) show that stereoscopic images from DEM are useful for tectonic geomorphology.
