National Vertical Datum - NZVD2016

The Cadastral Stream and the Positioning & Measurement Stream are pleased to jointly present a Webinar on the national vertical datum, NZVD2016.

While the datum has been in use for some time now, a number of Local Authorities have continued to require levels in terms of older local vertical datums. However, recent adoption of NZVD2016 by Local Authorities has increased and LINZ will require it for all surveys lodged after 1st July 2024. This is likely to further accelerate its adoption.

This webinar will be a refresher on the datum, describing how it is defined and how it differs from the earlier local vertical datums. It will discuss methods to establish new points by GNSS in terms of the datum, as well as various methods to transfer levels. It will also consider conversions between datums.

There will be comments from LINZ staff about the requirements for using the datum in cadastral survey datasets lodged after 1st July 2024.

Presenters for this webinar are Rachelle Winefield, Karl Wilton and David Stewart.

Webinar held Monday 10 June 2024, 12 pm
