Geodetic Marks App

The Land Information New Zealand (LINZ) Geodetic Marks app allows users to navigate to geodetic marks, access mark details, submit updated mark photos, and find key non-boundary marks that may need to be protected when engaging in earthworks.

New versions of the App for Android and Apple devices have been released.

The app is for anyone with an interest in locating geodetic and other important survey marks, including:

  • surveyors and other spatial professionals who use geodetic marks in their surveys
  • contractors who need to identify and protect survey marks near their works
  • trampers and other recreationalists who wish to find out more about trig stations they visit
  • land owners who are interested in the survey marks on their property.

In the new version of the app, you can:

  • find geodetic marks and other key non-boundary survey marks
  • navigate to marks using compass and distance, or Google Maps
  • access mark details, access diagrams and photos
  • submit updated mark details and photos to Toitū Te Whenua
  • advise Toitū Te Whenua of mark maintenance issues
  • create and save mark groups
  • add your own marks
  • identify distance to nearby PositioNZ GNSS CORS stations
  • toggle display between horizontal and vertical marks
  • filter displayed marks by coordinate order and beacon type.

The app is available for Android and Apple devices. If you are updating from a previous Android version, uninstall the older version first before installing the new version.
