Other dynamic spatial data

• Some data may not match a data cube structure.
  
• For example, spatiotemporal point patterns and trajectories.
  
• For these, the primary information is in the coordinates!

Spatiotemporal point patterns

• A set of spatiotemporal coordinates of events or objects (e.g., accidents, disease cases).

Trajectory data

• Trajectory data are time sequences of spatial locations of moving objects (e.g., people, animals, cars).
