This dataset provides an index to the Electronic Navigational Charts (ENC) available through the LINZ Data Service showing extent and ENC attributes.

The ENC index is compiled from the S-57 Object Class “Nautical publication information” which is used to relate additional nautical information or publications to the data. The attributes are populated by Land Information New Zealand’s (LINZ) production database.

S-57 is a standard used to exchange digital hydrographic data between hydrographic offices and to distribute this data to users.
This dataset was compiled for the use in the scale ranges 1:1,000 to 1:1,500,000 and smaller.

THIS DATA DOES NOT REPLACE NAUTICAL CHARTS AND MUST NOT BE USED FOR NAVIGATION.

This data is based on the S-57 data format used in ENCs, published and maintained by the New Zealand Hydrographic Authority at LINZ. Refer to the following link for information about S-57 data: www.linz.govt.nz/hydro/regulation/

A line connecting points of equal water depth which is sometimes significantly displaced outside of soundings, symbols and other chart detail for clarity as well as generalization. Depth contours, therefore, often represent an approximate location of the line of equal depth as related to the surveyed line delineated on the source. Also referred to as depth curve.

This index enables you to identify freely available digital bathymetric surface models owned by LINZ. This data provides a 3-dimensional model of the surface of the seafloor.

These surface models have been created by LINZ from publically funded single- or multi-beam data collected in the New Zealand coastal area since early 1998. The polygons in the index show the extent of these gridded data models, and include descriptive information, such as the age and quality of the data.

The gridded surface models are not downloadable from the LINZ Data Service, but can be provided to you on request.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset, and formats in which the data is available.

How to order the data:
Requests for the models should be sent to customersupport@linz.govt.nz with “Hydro Bathy Data” in the subject line. Requests must, as a minimum, specify the id and surf_name of the models of interest and the data format (see the options in Section 1.4 of the Bathymetric Data Dictionary).

LINZ has also created 3-dimensional bathymetric surface models for the New Zealand coastal area from data provided by third parties, which is subject to different licencing terms and conditions. View our "NZ Bathymetric Surface Model Index – Third Party" dataset to request this data.

This index enables you to identify the locations of current and historic sea level stations around New Zealand, on offshore islands (including Raoul Island, Chatham Islands and the sub-Antarctic islands), several South West Pacific islands and the Ross Dependency (Antarctica).

The attributes attached to each location will enable you to look up tidal levels, obtain relationships between tidal and land-based height datums, access tide predictions on LINZ’s website and find out how much sea level data LINZ has in its archive. See the LINZ website for official tide predictions.

View the attached data dictionary for detailed information about the attributes of this dataset.

Accessing sea level data
The data that is used to calculate tide predictions is also available. You can access publically available sea level data where a URL is provided in the data_link column.

For other locations, requests for sea level data should be sent to customersupport@linz.govt.nz with “Sea Level Data” in the subject line. Requests must, as a minimum, specify the location and time period that the data is required for.

Publically funded data can be released to the public under a Creative Commons licence for reuse. The provision of sea level data funded by third parties may be subject to some delay, as LINZ must obtain permission from the data owner. The owner may also attach conditions to the release of their data.

This index enables you to identify the freely available bathymetric data held and used by LINZ on its NZ coastal nautical charts. Some of our data holdings date back to the 1930s. The polygons comprising the index show the extent of the survey datasets. The attributes attached to each polygon will enable you to view, amongst other attributes, the age and quality of the bathymetric data.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset.

The bathymetric data is not downloadable from the LINZ Data Service. Datasets prior to the year 2000 are predominantly available only as georeferenced TIFF images of the original hard copy sounding sheets. Data post-2000 is often available as both georeferenced TIFF images and as digital data files (vector data in plain text format).

Requests for the bathymetric data should be sent to customersupport@linz.govt.nz with “Hydro Bathy Data” in the subject line. Requests must, as a minimum, specify the id, chart_no and serial_no as shown in the attributes attached to each polygon representing the datasets of interest.

LINZ also holds bathymetric data provided by third parties, which is subject to different licencing terms and conditions. View our "NZ Bathymetric Data Index – Third Party" dataset to request this data.

This dataset provides an index to the New Zealand Raster Charts available through the LINZ Data Service showing extent and Paper Chart attributes.

THIS DATA DOES NOT REPLACE NAUTICAL CHARTS AND MUST NOT BE USED FOR NAVIGATION.

The hydrographic raster data made available through the LINZ Data Service is based on the Paper Nautical Charts published and maintained by the New Zealand Hydrographic Authority at Land Information New Zealand (LINZ).

The NZ Paper Nautical Chart Index contains details of six international charts which are adopted by LINZ. Due to copyright reasons LINZ is not authorised to make the chart images available for download on LDS. These charts can be purchased from chart retailers.
