Topographic Layers

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

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.

This dataset consists of building outlines for the areas of Canterbury, Hawke’s Bay and Waikato, and is part of a pilot to understand the benefit of making building outlines data openly available through the LINZ Data Service.

Building outlines are 2D shapes of the edge of a building as visible from aerial imagery, most commonly the roofline edge. It includes spaces such as decks, garages and porches. Each polygon represents a building outline. The outlines were extracted in June 2016 from orthoimagery using an automated process.

Source imagery
Resolution of the imagery used for capture ranges from 50cm pixel resolution (0.5m GSD) to 10cm pixel resolution (0.1m GSD). Please refer to the ‘imagery_source’ attribute for details.

The following datasets on the LINZ Data Service were used in part or full in the creation of this dataset:
Waikato 0.5m Rural Aerial Photos (2012-2013)
Waikato District 0.1m Urban Aerial Photos (2014)
Hawkes Bay 0.3m Rural Aerial Photos (2014-15)

While some checks on the data have taken place, there are still errors present
*This is not a supported dataset and will be removed from LDS after the pilot

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.

The Topo50 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands, and offshore islands at 1:50,000 (some of the islands at 1:25,000) scale.

The Kermadec Islands data and maps, although captured and presented at 1:25,000 scale are, to all intents and purposes, part of the Topo50 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.

Please be aware of the following:

• The existence of a road or track does not necessarily indicate public right of access.

• Closed tracks are defined as being no longer maintained or passable and should not be used by recreationalists. The Department of Conservation or other authorities 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 forest and snow 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 islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.

In addition to contour lines, relief shading helps visualise the terrain. Hills and valleys are shaded as if they were illuminated from the north-west.

Relief layers were generated for each sheet, and specifically for use in the Topo50 map series. There may be subtle differences in the relief shading of adjacent map sheets. Where no contour information exists, relief shading has not been produced.

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.
