Date-Ship-Port triplet data based on AIS data

The data format consists of lines containing associations of ships with ports from AIS data. Triplets of date, ship, and port are provided to identify ship journeys between ports. This dataset was constructed using AIS data from the following sources: AISHUB (https://www.aishub.net/ ) NOAA (https://marinecadastre.gov/AIS/) DMA.DK (https://dma.dk/safety-at-sea/navigational-information/download-data)本数据集的数据格式为若干行记录，每行均包含源自船舶自动识别系统（AIS，Automatic Identification System）数据的船舶与港口关联信息。数据集提供了日期、船舶、港口的三元组，用以标识船舶在各港口间的航行行程。本数据集基于以下来源的AIS数据构建：AISHUB（https://www.aishub.net/）、NOAA（https://marinecadastre.gov/AIS/）、DMA.DK（https://dma.dk/safety-at-sea/navigational-information/download-data）
