Sentinel-2 + AIS Vessel Dataset

This dataset fuses Sentinel-2 optical remote sensing images with data from the Automatic Identification System (AIS) for vessels. It contains spatiotemporal information including multi-temporal satellite imagery, vessel positions, speed, course, ship type and other attributes, enabling accurate matching between spatial observations and dynamic trajectories. As a high-quality sample set, it can support inshore vessel monitoring and maritime target recognition. It addresses the limitations of single-source remote sensing data—such as susceptibility to cloud and fog interference and lack of vessel attribute information—and the absence of spatial context in AIS data. The dataset can underpin research in remote sensing-based vessel detection, spatiotemporal registration of multi-source data, abnormal navigation behavior identification, and maritime traffic supervision. It holds significant application value for improving the intelligent level of maritime supervision, ensuring inshore shipping safety, and conducting maritime rights and interests monitoring.
