对海岛礁及周边包括海浪、潮汐、潮流、温度等在内的复杂环境要素及其特点进行了分析。针对海洋复杂要素的特点,提出了适用于海洋高动态的面向可细分对象的时空数据模型,能够有效地对高动态及交互性较强的对象进行建模。以舟山群岛附近海域为例,对海岛礁及周边复杂环境进行了动态三维建模,并在Geoglobe等平台上进行了验证。实验表明,该模型对海岛礁及周边复杂环境建模有较好的实用性。
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.
