From static to dynamic datums: 150 years of geodetic datums in New Zealand

Abstract

The geodetic system in New Zealand plays an important role in the development of our country. It comprises intellectual, physical and data components which provide authoritative coordinate systems for New Zealand's areas of territorial and administrative responsibility. Measuring and mapping continues today with the management of our natural and economic resources becoming increasingly dependent on the availability of accurate and consistent spatial information. The foundation of our geographically based datasets, including the cadastral system, is an accurate national geospatial reference system, the ‘geodetic system’.
