Administrative Boundaries

• Throughout history boundaries have been used to
  divide the space around us into smaller units
• All of these boundaries have been established to
  facilitate administration, political and economic
  purposes

3
Example Boundaries

• Land market - Cadastre
• Collection of statistics - Collection district
• Facilitate mail delivery - Postcode
• Government - Local Government Areas
• Political boundaries - Electoral
  boundaries
• Natural boundaries - Catchment areas

Summary

• Worldwide unstructured methodologies for
  subdividing space have lead to the fragmentation
  of data between boundaries.
• This research aims to investigate new methods for
  the structuring of boundaries to facilitate data
  integration and exchange within the SDI.
