Bathymetric Indexes Data - Page 2

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 Southern Ocean/Ross Sea since 2004. 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 hydro@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).

This index enables you to identify the freely available georeferenced TIFF images of sounding sheets held by LINZ for the Antarctic (Ross Dependency) coastal area. Some of these sounding sheets date back to the 1950s. The polygons comprising the index show the extent of each original hard copy sheet - not just the soundings shown on the sheet. The attributes attached to each polygon will enable you to view, amongst other attributes, the date and scale of the bathymetric data shown on the sounding sheet.

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

The georeferenced TIFF images are not downloadable from the LINZ Data Service.

Requests for sounding sheets should be sent to hydro@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 sounding sheets of interest.

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.

Requests for the models should be sent to hydro@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.
