The Geometry of Uncertainty in Moving Objects Databases

  title={The Geometry of Uncertainty in Moving Objects Databases},
  author={Goce Trajcevski and Ouri Wolfson and Fengli Zhang and Sam Chamberlain},
This work addresses the problem of querying moving objects databases. which capture the inherent uncertainty associated with the location of moving point objects. We address the issue of modeling, constructing, and querying a trajectories database. We propose to model a trajectory as a 3D cylindrical body. The model incorporates uncertainty in a manner that enables efficient querying. Thus our model strikes a balance between modeling power, and computational efficiency. To demonstrate… CONTINUE READING
