New Zealand's geodetic system is the infrastructure that we use to accurately define the location and height of our land and sea.
Physically the geodetic system is seen as a network of trig stations and geodetic marks that spans the country. These are the reference points by which the location of all the features of New Zealand’s land and sea are defined.
These are the basis for creating maps and marine charts and in determining property boundaries. It is critical to the responsiveness of emergency services. It’s also vital for activities like construction and property development and the placement and location of utility services like power and gas. And it also provides information people rely on in daily life – for doing anything from tramping to driving.
Our job is to ensure this information is suited to the needs of the people who use it. We make sure the methods used to measure, store and convert this data are sound, and that what we do and how we do it is compatible with international standards.
