Dynamic visual simulation of construction project based on GIS

With the development of computer graphic technology and popularization of simulation, visualization applied in simulation has been an important trend in advanced simulation technology. Visualization can describe information difficult for expression, and is convenient for information communication, as well as accelerating modeling, improving simulation efficiency, and reducing the operation level. This paper combines geographic information system (GIS) and simulation technology providing output system of large construction three dimension dynamic visual simulation based on GIS to realize simulation process and visualization of simulation result. This approach changes traditional simulation pattern which can directly reflect complex time space logic relations among construction activities, clarify inner dynamic action characteristics of construction system, and provide a powerful tool for comprehensive understanding construction quickly in whole life cycle and for comparative analysis of multi-projects.
