A visualized 3D terrain model of Bohai Straitcrossing tunnel is established, so as to analyze the alignment arrangement of the tunnel and to decide the modeling scope of the tunnel. The ASTER GDEM data are adopted as the resources for Bohai strait terrain; and then they are turned into DED mode. The technologies, OpenFlight data structure, LOD technology and modeling method of Delaunay triangle surface, are analyzed. The structural design and modeling sequence design of 3D terrain modeling system are made. Finally, the 3D terrain with good effect is established and the visualized model of local terrain of the tunnel alignment is established, so as to provide foundation for the planning of Bohai Straitcrossing tunnel.
Key words: Bohai Strait; seacrossing tunnel; 3D terrain; visualized modeling
