中文摘要：

为直观地探究GPS、AIS、雷达和VTS等助航设备产生的信息中隐藏的有价值的信息,需对这些信息进行可视化,因此对水上交通信息可视化技术的研究进展情况进行论述.首先,从数据处理、可视化呈现、人机交互和可视化工具等方面阐述信息可视化关键技术;然后,从轨迹可视化、密度可视化和属性可视化等分析水上交通的可视化任务,并列举几个典型的应用实例;最后,总结水上交通信息可视化面临的挑战和发展方向.该研究可为海事监管人员掌握水上交通流的特征、分析船舶行为和评估航行风险等提供一种新的技术手段.

英文摘要：

Information from GPS, AIS, Radar, VTS and other aids to navigation is of ＇ big data＇ feature. In order to ex- plore the data for valuable hidden information, the data need to be visualized. The maritime traffic information visualization techniques will provide maritime supervisors with a powerful technical means to grasp the features of the maritime traffic flow, to analyze the behavior of vessels, assess navigation risks and so on. The progress of visualization techniques in mari- time traffic information presentation is reviewed, covering the key techniques and tools applied to information visualization, including data processing, visual presentation, human-computer interaction. The tasks and typical applications of maritime traffic information visualization are described, covering trajectory visualization, density visualization and attribution visualization. The prospects of maritime traffic information visualization and the challenges it faces are analyzed.
