Dynamic 3D Modeling of Island,Reef and Surrounding Complex Environment

This paper analyzes the characteristics of island,reef and complex environment including sea wave,tide,tidal current and temperature.Then,based on the features of marine complex elements,subdividable object oriented data model(SOODM) has been put forward which applies to high dynamic and strong interactive object effectively.Finally,this paper takes pilot of Zhoushan Islands and realizes the dynamic three-dimensional(3D) modeling of island,reef and surrounding complex environment.The model has been examined on Geoglobe and the result shows the validity and practicability of this model
