WebMap construction is a data-mining technique that automatically produces street maps from trajectory data . This paper proposes a new method that constructs maps (i.e., shipping routes) from vessel-movement data. ... Point clustering regards trajectories as sets of points, and generates maps by clustering these points . A K-means clustering ... WebFinally, as shown in Figure 3e,f, the HC trajectories were considered in all clusters with the majority of them (55%) being found in the MPAS/EPDS cluster 2, followed by cluster 1 with 40% of all HCs, clusters 1 and 2 taken as baseline clusters. The remaining 5% of HCs were shared by the two U-shaped clusters.

WebMay 4, 2024 · Clustering Trajectory Points. For clustering trajectory points, we chose the DBSCAN algorithm proposed by Ester et al. to cluster spatial points.Users are required to input two parameters: neighborhood radius (r) and density threshold of the core area (Minpts) (Fig. 2).The core point is defined as the point whose neighbor point count is no … WebMay 27, 2024 · We propose a model for subtrajectory clustering---the clustering of subsequences of trajectories; each cluster of subtrajectories is represented as a pathlet, a sequence of points that is not necessarily a subsequence of an input trajectory. Given a set of trajectories, our clustering model attempts to capture the shared portions between … WebMar 21, 2024 · A multiple clustering algorithm based on high-dimensional automatic identification system (AIS) data is proposed to extract the important waypoints in the ship’s navigation trajectory based on selected AIS attribute features and construct a route network using the waypoints.
