Gravity and the geoid

/guidance/geodetic-system/coordinate-systems-used-new-zealand/vertical-datums/gravity-and-geoid

Geoids and quasigeoids are reference surfaces that accurately represent the Earth’s shape and gravitational field. By collecting gravity data (which differs with latitude, elevation, geology and time), gravity field models are created to compute the geoid, which is then used as reference for a vertical datum.

PositioNZ - Real Time Service

/products-services/geodetic/positionz/positionz-real-time-service

The Toitū Te Whenua PositioNZ Real Time Service (PositioNZ-RT) streams GNSS (including GPS and GLONASS) data in real time. This free service allows users of real-time GNSS equipment to obtain positions in terms of New Zealand Geodetic Datum 2000 (NZGD2000) without having to set up their own base station.

Investigations in support of PositioNZonLine

/resources/research/investigations-support-positionzonline

With the planned release of the PositioNZ-PP on-line GPS procession tool, LINZ requires updated models to predict forward the position of each of the continuous GPS reference stations of the PositioNZ network and transformation parameters between NZGD2000 and the current GNSS reference frame. This report summarizes the results of Otago University School work in these two areas.
