Oceania Layers - Page 12

As of June 2017, this dataset has been replaced by the NZ Roads (Addressing) and NZ Roads Subsections (Addressing) datasets and will no longer be updates. See NZ Roads Data Dictionary for field mappings to the new dataset.

This source Landonline data exists in order to provide linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

A road centreline in this layer will typically consist of several road centreline geometries from Landonline that have been associated to the same road name.
In Landonline a road name is commonly assigned to multiple stretches of roading such as between intersections with other roads. A road name is also commonly duplicated across the country e.g. "Queen Street", "High street" etc.

For this layer (as opposed to the Road Subsections Layer. Individual road sections have been aggregated to a single road centreline geometry for each locality. Thus, for example, State Highway 1 has individual sections for differing towns and whenever it crosses a Territorial Authority boundary.

Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation.

The road centrelines recorded in Landonline do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal.

As a general rule those that are not within a Road Parcels Layer should be treated as being of highly variable accuracy. They do however meet the purposes for which they have been captured, and can provide a valuable resource for other purposes provided that the user(s) understand their origin and consequential limitations.

Warning:
The purpose of the location field is to enable differentiation between roads of the same name in the dataset. It should not be considered official nor part of a valid postal address. It can however be used as an indicative guide to location within a Territorial Authority, or in the case of regional road networks, as an indicative guide to location within New Zealand.

This layer provides Land District shapes and their name.

A Land District is an administrative area that all titles and surveys were registered against prior to Landonline. It is required to uniquely identify survey and title records created prior to Landonline.

This dataset provides a seamless cloud-free 10m resolution satellite imagery layer of the New Zealand mainland and offshore islands.

The imagery was captured by the European Space Agency Sentinel-2 satellites between December 2016 - December 2017.

​

Currency This data will be updated once a year, during the term of the 2-year pilot.

Technical specifications It comprises 450 x ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:50,000 tile layout.

• Satellite sensors: ESA Sentinel-2A and Sentinel-2B
• Acquisition dates: December 2016 - December 2017
• Spectral resolution: R, G, B
• Spatial resolution: 10 metres
• Radiometric resolution: 8-bits (downsampled from 12-bits)

This is a visual product only. The data has been downsampled from 12-bits to 8-bits, and the original values of the images have been modified for visualisation purposes.

If you require the 12-bit imagery (R, G, B, NIR bands), send your request to eo@linz.govt.nz

This layer contains the DEM for LiDAR data from the Auckland region captured in 2013.
The DSM is available as layer Auckland Lidar 1m DSM (2013).
The index tiles are available as layer Auckland Lidar Index Tiles (2013).
The LAS point cloud and vendor project reports are available from OpenTopography.

Lidar was captured for Auckland Council by NZ Aerial Mapping & Aerial Surveying Limited. The capture of the data commenced on 17th July and was completed by the 23 November 2013. The datasets were generated by both ASL and NZAM. All raw point cloud data was produced by NZAM & ASL prior to data being sent to Genesys International for the data classification and product generation.

The physical Crown Aerial Film Archive is managed for LINZ by WSP New Zealand. Most Crown photographs have been scanned and are available digitally from LINZ upon request. See the Crown Aerial Film Archive historical imagery scanning project for direction on how to access the digitised photos. The photos are not downloadable from the LINZ Data Service.

​

Photos not yet digitised by be ordered from WSP NZ. You will need to provide the survey, run, and photo number (values in the ‘SURVEY’, 'RUN', and 'PHOTO_NO' attributes) covering your area of interest. WSP NZ will be able to provide information about the cost of providing images in various formats. Contact them at WSP Photo Sales.

​

The New Zealand Aerial Mapping photo archive has been aquired and added to the Crown Aerial Film Archive. These images will also become available from LINZ once digitised or may be ordered from WSP NZ.
