This dataset was last updated on LINZ Data Service on 26 Mar 2019.

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 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).

This index enables you to identify the freely available bathymetric data held and used by LINZ on its Antarctic (Ross Dependency) coastal nautical charts. Some of our data holdings date back to the 1960s. 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.

This layer contains all individual vector layers for the Ant50 map series available through the LINZ Data Service. Ant50 is the topographic mapping carried out by LINZ within the Ross Dependency, Antarctica.

This grouping of NZ Ross Dependency Topo50 Data layers will allow you to quickly view and
download this collection of related layers

See the Topographic Data Dictionary for detailed information about each layer, and our background information on the Antarctic Topo50 map series for more information about the data, including update history and release notes.

The Ant50 map series provides topographic mapping within the Ross Dependency, Antarctica

Digital images of the maps are also publicly available from www.linz.govt.nz/topography/topo-maps/antarctic-to...

Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.
