The automatic identification system (AIS) provides a massive database for ocean science.
The original AIS data are redundant. Direct use will cause a waste of data storage space …

Vessel trajectory data are currently the most important data source for vessel trajectory data
mining research. However, vessel AIS data have a short sampling time interval and a large …

Ship trajectory data extracted from Automatic Identification System (AIS) has been
extensively used for maritime traffic analysis. Yet the enormous volume of AIS data has …

Map matching is a widely used technology for map** tracks to road networks. Typically,
tracks are recorded using publicly available Global Navigation Satellite Systems, and road …

Most trajectory compression methods primarily focus on geometric similarity between
compressed and original trajectories, lacking explainability of compression results due to …

Most traditional trajectory compression methods, such as the Douglas–Peucker (DP)
method, consider only spatial characteristics and disregard contextual factors, including …

The Automatic Identification System (AIS) is extensively used in monitoring vessel traffic, and
ship navigation related information can be obtained from the AIS data. However, AIS data …

With the rising popularity of portable mobile positioning equipment, the volume of mobile
trajectory data is increasing. Therefore, trajectory data compression has become an …

Simplifying trajectory data can improve the efficiency of trajectory data analysis and query
and reduce the communication cost and computational overhead of trajectory data. In this …

Nowadays anomalous trajectory detection has a prominent place in many real-world
applications. In this paper, firstly, we have proposed a comparison between two Deep …
