基于AIS的台湾海峡西岸中南部水域航迹偏移定量分析

Quantitative Analysis of Ship Track Deviations in the Central and Southern Waters of the Taiwan Strait Based on AIS

以2014~2016年船舶AIS数据为基础,对台湾海峡西岸中南部水域AIS船舶轨迹分布进行了统计分析。结果显示,研究水域内的AIS船舶航迹不同程度地发生了向东偏移的现象。其中厦门湾和东山湾断面向东偏移量较明显,为0.6海里;海坛海峡断面向东偏移量约0.3海里。

Based on the ship AIS data from 2014 to 2016,a statistical analysis of the trajectory distribution of AIS ships in the central and southern waters of the Taiwan Strait was carried out.The results show that the AIS ships in the study waters have quite the same eastward trajectories in different levels among them,the eastward offset of the Xiamen Bay and Dongshan Bay section is obviously 0.6 nautical miles,and the eastward offset of the Haitan Strait section is about 0.3 nautical miles.
