Trajectory Indexing Using Movement Constraints*

  title={Trajectory Indexing Using Movement Constraints*},
  author={Dieter Pfoser and Christian S. Jensen},
With the proliferation of mobile computing, the ability to index efficiently the movements of mobile objects becomes important. Objects are typically seen as moving in two-dimensional (x, y) space, which means that their movements across time may be embedded in the three-dimensional (x, y, t) space. Further, the movements are typically represented as trajectories, sequences of connected line segments. In certain cases, movement is restricted; specifically, in this paper, we aim at exploiting… CONTINUE READING
