Moving Object Databases in Space Applications

• Moving Object Databases in Space Applications
• Build an application framework for a MOD
• Oracle Spatial 10g is the spatial database
• JDBC database connectivity
• Oracle Spatial SDOAPI Java Class Library handle
  spatial data
• Moving Objects simulation
• Simulator using Java (Swing) GUI
• Movements of objects tracked by simulation
• Co-ordinates of objects are updated
• Spatial data retrieved and map is created with
  locations
• Moving objects simulator creates moving objects

• Abnormal Traffic due to accidents, extreme
  climatic conditions
• Sources traffic sensors/detectors on highways
• Construction of trajectory
• Updating trajectory
• Spill-over effect in case of abnormal traffic
• Identifying trajectory
• Affected trajectories in MOD
