Novel robust multilevel 3D visualization technique for web based GIS

Number of recent technologies take Geographic Information Systems to new levels of power and usability. One of the most promising technologies that empower Geographic Information Systems is the 3D GIS modeling. In this paper, a novel robust multilevel data structure model called EBOT model (block octree tetrahedron mode Geographic Information Systems l) is presented on the basis of BOT visualization model. This model combines octree and Tetrahedral Network structures. In this paper a performance simulation for implementing EBOT (Enhanced block octree tetrahedron model) algorithm into the browser using X3D Visualization is presented. A Simulation results is introduced to demonstrate the robustness of the
