3D Modeling of Reconstruction Plan at Sanriku Coast for Great East Japan Earthquake: Visualization of the Reconstruction Plan for Effective Information Sharing

In this paper, we propose our approach to speed up the reconstruction of city, village, and town at Sanriku coast areas, which had unprecedented damages in the Great East Japan Earthquake that occurred on March 11, 2011. There are two policies in our approach. One is to build 3D models of the reconstruction plans in order to visualize reconstruction plans, and the other is to develop human resources that can build 3D models of reconstruction plans by setting up training courses. They can teach the modeling method to another people, and assist the reconstruction and accelerate the whole of recovery. The professional education (teaching) contents involve both 3D CAD (Computer Aided Design) and 3D CG (Computer Graphics). Since the constructed 3D models involve CAD topographic map, aerial photographs, geography and attribute information of the road, river, rail way and so on, it is easy for residents to understand the whole reconstruction plans. In fact, these 3D models are definitely effective for residents briefing and confirmation of urban planning.
