Environment Canterbury


  • Difficult undersea terrain and marine installations stretch across the East Coast of New Zealand’s South Island.
  • Manual monitoring of vessel traffic and movements was resource intensive and subject to human error.
  • There was an urgent need to leverage marine data from multiple sources for improved risk management.

  • The solution uses virtual AtoNs to mark pilot stations and to replace physical AtoNs that are difficult to maintain.
  • Overlaying of AIS data with information from other sources eliminates manual data mapping.
