LINZ has released a new vertical datum – a reference system for measuring heights.
This is essential data for understanding the height of our land and its features, and so can help researchers and planners predict how water will flow during a flood or storm.
It will also enable engineers to consistently locate underground services, surveyors to efficiently define three-dimensional property boundaries and scientists to reliably measure changes in sea level.
The project to update the vertical datum has been led by LINZ in partnership with Victoria University and GNS Science.
