The NZ Elevation Survey Index dataset provides an index to all LiDAR derived elevation datasets found on the LINZ Data Service. Each record in the dataset provides both a geometry of the extent of the elevation survey, as well as useful metadata attributes. The extents are derived from the maximum extent of DEM and DSM coverage and consist of full NZTopo50 1k tiles, even where a tile is only partially covered with data. These extents only provide a rough indication of corresponding point cloud coverage which can be quite different for some elevation surveys.

Please refer to the NZ Aerial Surveys Data Dictionary for detailed metadata and information about this dataset.

The elevation data referenced by this dataset is available on the LINZ Data Service.

This dataset was first added to LINZ Data Service on 06 Aug 2019.

This dataset provides river name lines for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service.

Unnamed rivers are also included in this dataset.

How this data can be used

Together with the NZ River Name Polygons (Pilot) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river).

We want your feedback

To provide feedback on these pilot datasets, please complete our short survey.
Your feedback will be used to help inform future enhancements to LINZ river datasets.

Data vintage

The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata.
Please refer to the NZ River Name Lines and Polygons (Pilot) Data Dictionary for detailed metadata and information about this dataset.

Related data

NZ River Name Polygons (Pilot) - contains larger rivers captured as polygon features instead of lines.

We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features.

The NZ River Name Lines and Polygons (Pilot) Data Dictionary provides details on how to download the matching time period snapshots of this data.

Please note

  • Official geographic names as listed in the New Zealand Gazetteer of place names must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

  • This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets.

This dataset provides building outlines within mainland New Zealand extracted from multiple years of aerial imagery, allowing you to see change over time, or restrict the dataset to building outlines that match a specific aerial imagery source.

A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline.

Building roof outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset contains all building outlines which have been extracted from multiple years of aerial imagery available in each region of the country, including the most recent imagery. This dataset includes the dates for which each building existed in the aerial imagery.

Coverage areas include Northland, Auckland, Waikato, Hawke’s Bay, Manawatu-Whanganui, Wellington, Taranaki, Tasman, West Coast, Marlborough, Canterbury, Southland and Otago. This dataset will be updated and expanded as new aerial imagery becomes available.

Please refer to the NZ Building Outlines Data Dictionary for detailed metadata and information about this dataset.

Related building outlines data

NZ Building Outlines Lifecycle – stores the relationship between building outlines when one building is split into two or more building outlines, or when multiple building outlines are merged into a single outline. Use this in conjunction with the NZ Building Outlines (All Sources) dataset.

NZ Building Outlines - provides current building outlines only, derived from the latest LINZ aerial imagery.

A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline.

Building outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset shows the most recent set of building outlines extracted from the LINZ aerial imagery available on the LINZ Data Service.

Current coverage includes areas in Northland, Auckland, Waikato, Hawke’s Bay, Manawatu-Whanganui, Wellington, Tasman, Taranaki, West Coast, Marlborough, Canterbury, Southland and Otago. This dataset will be updated and expanded as new aerial imagery becomes available.

Since aerial imagery is flown only every few years in each region of the country, building outlines only reflect those buildings observed at the date of this aerial imagery capture, and may not reflect buildings constructed after this time period.

Please refer to the NZ Building Outlines Data Dictionary for detailed metadata and information about this dataset.

This dataset was first added to LINZ Data Service on 20 Dec 2017.

When New Zealand Aerial Mapping (NZAM) went into liquidation in September 2014, LINZ took ownership of their historic archive, and these photos are now available to the public.

This layer has been provided to enable potential users to identify the coverage of aerial photography for Mainland NZ flown by NZAM for private contract work between 1939 and 2008. These surveys compliment the Historic Aerial Photos, Survey Footprints, CROWN (1936-2005) layer which is currently being scanned.

If you are aware of any inaccuracies, please contact LINZ: info@linz.govt.nz or +64 4 4600110. The layer shows the approximate bounding box of each aerial survey undertaken.

How to Access Photos:
The Collection exists as photographic negatives which are not in digital form so the images are not downloadable.

The Collection is managed for LINZ by WSP Opus International. You can order images from the Collection from Opus NZ in a number of formats, including:

  • contact prints
  • enlargements
  • digital files
  • precision scans for photogrammetric production
  • orthophotos

You will need to tell Opus NZ the survey number (the value in the ‘survey’ attribute) covering your area of interest and the name of the survey.

Opus NZ will be able to provide information about the cost of providing images in the various formats. Contact them at: photosales@opus.co.nz or 0800 680 690

There are a small number of surveys that have not been referenced in the LDS layers due to incomplete metadata. Opus NZ will be able to let you know if additional photographs are available in your area of interest.
