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.
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 firstname.lastname@example.org 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 New Zealand coastal area, which can be readily released under a Creative Commons licence for reuse. View our "NZ Bathymetric Surface Model Index" dataset to request this data.
