  • 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 New Zealand coastal area since early 1998. 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). LINZ has also created 3-dimensional bathymetric surface models for the New Zealand coastal area from data provided by third parties, which is subject to different licencing terms and conditions. View our "NZ Bathymetric Surface Model Index – Third Party" dataset to request this data.

  • The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham Islands, offshore islands, and offshore dependancies at 1:50,000 (some of the islands at 1:25,000) scale. For some small islands the printed map scale is 1:25,000. Although presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series. Along with the paper-based Topo50 map series, digital images of the maps are also publicly available. 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. For more information, and a description of the georeferencing keys: http://www.linz.govt.nz/topography/topo-maps/topo50/digital-images Please be aware of the following: - The existence of a road or track does not necessarily indicate public right of access. - The Ministry of Infrastructure and Planning, Rarotonga, should be contacted for the latest information on tracks and huts. - Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data. - Contours and spot elevations in vegetation areas may be less accurate. - Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies -Permits may be required to visit some sensitive and special areas. Contact the Ministry of Infrastructure and Planning, Rarotonga, to see if you need to apply for a permit.

  • Geographic name holds the proper noun of certain objects within the Topo databases. Geographic_name does not apply to roads, railway lines, or descriptive text - eg 'Brunner Mine' would be a Geographic_name but 'mine disused' is held in the descriptive_text feature Data Dictionary for geographic_name: https://docs.topo.linz.govt.nz/data-dictionary/tdd-class-geographic_name.html This layer is a component of the Topo50 map series. The Topo50 map series provides topographic mapping for New Zealand and it's offshore dependancies, at 1:50,000. For some small islands the printed map scale is 1:25,000. Although presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series. Further information on Topo50: http://www.linz.govt.nz/topography/topo-maps/topo50
