Emergency Routing Approach Based on the 3D GIS

LI Yuan  
Quick and reliable vehicle routing and navigation are crucial for urban emergency response and disaster management. With the analysis of the characteristics of emergency response,such as multi-dimension,dynamics,uncertainty,etc.,and the shortcomings of traditional 2D planar network,a 3D dynamic network,as well as corresponding optimization method is developed,followed by the discussion of weighting approach for multi-dimensional information. Based on which,this paper constructs a 3D GIS based emergency routing approach in VGEGIS software,with the capacity of 3D route finding in realistic emergency situation.
