SW Pacific Bathymetric Surface Model Index – Third Party
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 email@example.com 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.
The purpose of this dataset is to provide an index to the 3-dimensional bathymetric surface models created by LINZ from third party funded single- or multi-beam data collected since 2005 in the SW Pacific. The index enables customers to identify data that they may be interested in requesting from LINZ for their own use.
The Royal New Zealand Navy and, more recently, LINZ have received bathymetric data from third parties which has been incorporated into nautical charts to enable New Zealand to meet its obligations under the International Convention for the Safety of Life at Sea.
This index has been derived from extents and information derived from 3-dimensional bathymetric surface models created by LINZ from third party single- or multi-beam data collected in the SW Pacific since 2005.
LINZ’s bathymetric data is usually based on minimum seabed depth (shoal-biased) values. This means if two soundings are close together we choose the lesser (shallower) one as safety is our primary concern.
