Abstract

•Position information and velocity direction are used for trajectory segmentation.•A new similarity matrix is construct for clustering.•The spatial R-tree index is used to improve the efficiency of neighborhood query.•The real Atlantic hurricane and elk datasets verify that the proposed algorithm.
