This report updated Cabinet in November 2022 on the progress of SouthPAN, Toitū Te Whenua and Geoscience Australia’s joint initiative to improve the accuracy of global positioning signals in Australia and New Zealand.

This report updated Cabinet in May 2023 on the progress of Toitū Te Whenua and Geoscience Australia’s joint SouthPAN satellite initiative to improve the accuracy of global positioning signals in Australia and New Zealand.

The purpose of the 2023 New Zealand Geospatial Industry Profile Survey was to gain demographic and employment information about the geospatial industry in New Zealand.

The purpose of the survey was to determine the relationship between the permanent GNSS CORS site (WARK 50243M001), the invariant reference points (IVP) of the 12 metre (7377 50243S001) and 30 metre (7391 50243S002), radio telescopes capable of Very Long Baseline Interferometry (VLBI) observations.

The request relates to specific information about NZVD2016 Cadastral Vertical Control Marks and evidence to indicate how values attributed to these were derived.

The purpose of this standard is to ensure that the geospatial accuracy framework (LINZS25005) is consistently applied across LINZ cadastral survey and control system datasets

This fact sheet supersedes LINZG25702 Fact sheet - New Zealand Geodetic Datum 2000 Projections which was published in November 2007.

This fact sheet describes the Ross Sea Region Geodetic Datum 2000 (RSRGD2000).

The purpose of this standard is to both define the Ross Sea Region Geodetic Datum 2000 and detail the parameters that define it.

This report compares currently available transformation parameters for converting between NZGD49 (New Zealand Geodetic Datum 1949) and WGS84 (World Geodetic System 1984) coordinates.

With the establishment of a new datum comes a need to transform coordinates from one datum to the other as only a small number of marks have been surveyed in terms of both datums.

The 4 September 2010 Darfield (Canterbury) earthquake resulted in up to 5 metres of lateral slip along the previously unknown Greendale Fault (Figure 1) and associated ground surface displacements of up to about 2.5 metres within the surrounding region (Quigley et al., 2010, 2012; Beavan et al., 2010). Land Information New Zealand (LINZ) requires a way to correct and update the survey system for the effects of the earthquake.

These specifications relate to the provision of geodetic control maintenance to support the geodetic programme as required by the Cadastral Survey Act 2002 sec 7(1)(a) and (b).

This report examines height datum technologies and also looks at current international practice with respect to height datum issues. It presents some wider user perspectives before looking more specifically at the physical characteristics of New Zealand and the particular problems that it faces.

This report is the response to a brief from Land Information New Zealand (LINZ) to establish the economic foundation for funding a modern geodetic system for New Zealand.
