Location data becomes more and more important. In this paper, we focus on the trajectory data, and propose a new framework, namely PRESS ( P aralleled R oad-Network-Based Trajectory Compr ess ion), to effectively compress trajectory data under road network constraints. Different from existing work, PRESS proposes a novel representation for trajectories to separate the spatial representation of a trajectory from the temporal representation, and proposes a Hybrid Spatial Compression (HSC… Expand
