This dataset was first added to LINZ Data Service on 07 Oct 2019.

The Bluff 1955 to NZVD2016 Conversion Raster provides users with a two arc-minute (approximately 3.6 kilometres) raster image of the conversion of normal-orthometric heights from the Bluff 1955 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016).

The conversion value is represented by the attribute “O”, in metres.
This conversion and NZVD2016 are formally defined in the LINZ standard LINZS25009.

The height conversion grid models the difference between the Bluff 1955 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy is better than 2 centimetres (95% Confidence interval).

More information on converting heights between vertical datums can be found on the LINZ website.

06 Aug 2019

This dataset was first added to LINZ Data Service on 06 Aug 2019.

This dataset provides river name lines for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service.

Unnamed rivers are also included in this dataset.

How this data can be used

Together with the NZ River Name Polygons (Pilot) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river).

We want your feedback

To provide feedback on these pilot datasets, please complete our short survey.
Your feedback will be used to help inform future enhancements to LINZ river datasets.

Data vintage

The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata.
Please refer to the NZ River Name Lines and Polygons (Pilot) Data Dictionary for detailed metadata and information about this dataset.

Related data

NZ River Name Polygons (Pilot) - contains larger rivers captured as polygon features instead of lines.

We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features.

The NZ River Name Lines and Polygons (Pilot) Data Dictionary provides details on how to download the matching time period snapshots of this data.

Please note

  • Official geographic names as listed in the New Zealand Gazetteer of place names must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

  • This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets.

These topographic trig points are derived from New Zealand geodetic marks data which can also be accessed through the LINZ Data Service: NZ Geodetic Marks and NZ Geodetic Vertical Marks.

This layer is a component of the Topo50 map series. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham and New Zealand's offshore islands, at 1:50,000 scale.
