Vessel Traffic Density from AIS Data (2013-2015)

Maps of vessel density 2013-2015 for AIS-equipped vessels, in terms of km traversed in each cell for range of vessel classes for the Australian EZ. AIS data was sourced from AMSA and subsequently processed. The density was calculated for subsets of vessels based on various characteristics such as size or vessel use/purpose. These characteristics were derived and may contain errors.

See Peel et. al. (2018) for detail on the processing methods.

本数据集涵盖2013-2015年配备自动识别系统（Automatic Identification System，AIS）的船舶在澳大利亚专属经济区（Exclusive Economic Zone，EZ）的船舶密度地图，以各网格单元内的累计航行千米数为统计基准，涵盖多个船舶类别。
AIS数据由澳大利亚海事安全局（Australian Maritime Safety Authority，AMSA）提供并经后续处理。密度计算基于不同船舶特征子集，例如船舶尺寸、使用用途等。上述船舶特征为推导所得，或存在误差。

有关处理方法的详细细节，请参见Peel等人（2018）的研究成果。
