Seaweed is the general name for marine plants of the Algae class which grow in long narrow ribbons. Kelp is one of an order (laminariales) of usually large, blade-shaped or vine-like brown algae.

S-57 Object Class: Weed/Kelp

S-57 Acronym: WEDKLP

This data was compiled for the use in the scale range 1:90,000 to 1:350,000.

The DUN58-NZVD2016 grid enables the conversion of normal-orthometric heights from the Dunedin 1958 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016).

The conversion value is represented by the attribute “O”, in metres.

This conversion and NZVD2016 are formally defined in the LINZ standard LINZS25009.

DUN58-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Dunedin 1958 vertical datum (168.4° E to 171.3° E, 43.9° S to 46.5° S).

The height conversion grid models the difference between the Dunedin 1958 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of DUN58-NZVD2016 is better than 2 centimetres (95% Confidence interval).

More information on converting heights between vertical datums can be found on the LINZ website.

The DUN58-NZGD2000 grid enables the conversion of normal-orthometric heights from the Dunedin 1958 local vertical datum directly to New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights.

DUN58-NZGD2000 is published on a one arc-minute grid (approximately 1.8 kilometres) extending over the benchmarks that nominally define the extent of the Dunedin 1958 vertical datum (168.4° E to 171.3° E, 43.9° S to 46.5° S).

The conversion value is represented by the attribute “delta”, in metres.

This grid is a combination of New Zealand Quasigeoid 2016 NZGeoid2016 and the DUN58-NZVD2016 height conversion grid. Where NZGeoid2016 is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016), while the DUN58-NZVD2016 grid models the difference between the Dunedin 1958 vertical datum and NZVD2016 using the LINZ GPS-levelling marks.

This index enables you to identify the third party bathymetric data held and used by LINZ on its NZ coastal nautical charts. Some of our data holdings date back to the 1950s. 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 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 datasets of interest.

The provision of third party funded bathymetric data may be subject to some delay as LINZ confirms 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 New Zealand bathymetric data, which can be readily released under a Creative Commons licence for reuse. View our "NZ Bathymetric Data Index" dataset to request this data.
