Hydrographic & Maritime Data

This index enables you to identify digital bathymetric surface models covering the South West Pacific created by LINZ using third party data. This data provides a 3-dimensional model of the surface of the seafloor.

These surface models have been created by LINZ from third party single- or multi-beam data collected in the South West Pacific since 2005. 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 requested.

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).

It may take a few days to get the surface models generated from third party funded bathymetric data to you, as we need to confirm with the data owner that they are happy for their data to be released. The owner may attach conditions to the release of their data.

LINZ also holds publically funded bathymetric data for the South West Pacific, which can be readily released under a Creative Commons licence for reuse. View our "SW Pacific Bathymetric Surface Model Index" dataset to request this data.

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

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/

This index enables you to identify digital bathymetric surface models created by LINZ using third party data. This data provides a 3-dimensional model of the surface of the seafloor.

These surface models have been created by LINZ from third party single- or multi-beam data collected in the New Zealand coastal area since 2009. 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 requested.

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.
