3D Visualization of Seismic Buildings in Yushu Earthquake for Disaster Management

The 2010 Yushu earthquake caused tremendous life and economic loss in Yushu county, Qinghai, China. More than hundred thousand buildings were totally or partially collapsed. This paper focuses on the 3D visualization of disaster environment in both coarse scale and fine scale for further disaster management. In the study area, different data resources were used in different scales for different purpose. Information extraction of building's attributes from high-resolution remote sensing images was presented. The results obtained from this project indicted that it is very feasible and reliable for 3D visualization of seismic building in such a distractive earthquake.
