Preprocessed AIS Dataset

Contains 2482 days of downsampled AIS data. Data includes: point id, time, lat, lon, course (relative to north), speed (in knots), and vessel id (MMSI).Batch/row group in the parquet file represents the day. Due to various issues in downloading the dataset, some days are skipped, so this is not a reliable indication of the actual date, but dataset ranges from Jan 1 2015 to Mar 31 2024.
