Scene simulation has been widely used in many fields recently as an outstanding technology. Firstly, this paper introduces the development flow and the modeling technologies of the scene database based on the characteristics of the scene simulation system. Then, the optimization technologies of modeling in constructing the scene simulation database are illuminated. In conclusion, the paper successfully established the scenedatabase of a port with the digital elevation model data and satellite images. The experiment of scene simulation has been done with Vega Prime. The results show that it solves the conflicts of models between complexity and fidelity very well. It runs smoothly and almost meets the demands of voyage training.

Floods usually cause large-scale loss of human life and wide spread damage to properties. Determining flood zone is the core of flood damage assessment and flood control decision. The aim of this paper is to delineate the flood inundation area and estimate economic losses arising from flood using the digital elevation model data and geographic information system techniques. Flood extent estimation showed that digital elevation model data is very precious to model inundation, however, in order to be spatially explicit flood model, high resolution DEM is necessary. Finally, Analyses for the submergence area calculation accuracy.
