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 provides the latest bearing (direction) and/or distance for cadastral boundaries.

When a cadastral survey is undertaken the relationship between boundary and non-boundary marks is ascertained or measured.
• This commonly is in the form or a vector (bearing and distance), but occasionally just one component.
• Some relationships are defined as arcs. In this data layer, the arc length is recorded in the distance field and a separate record holds the chord.

Only observations that have been captured in Landonline are available. This includes vectors that were re-captured in the Survey Capture Areas from survey plans lodged prior to Landonline and all survey observations since.

This layer shows the New Zealand mainland sheet extents for the historic NZMS 260 map series.

The NZMS 260 Topographic map series began in 1977 and ended production in 2009. The series was produced at the 1:50,000 scale.

NOTE: The NZMS260 map series has now been superseded by NZTopo50. To download the NZTopo50 Map sheets please refer to NZ Topo50 Map Sheets. For further information and latest editions of Topographic maps for the whole of New Zealand see here.

Orthophotography over Auckland City taken in the flying season (summer period) 2015 -16.

Imagery was captured for the ‘Auckland Council’ by AAM NZ Limited, 6 Ossian St, NAPIER, New Zealand.

Data has subsequently been provided to LINZ and this comprises:
• 4,835 x ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:1,000 tile layout
•Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. The products are tiled into NZTopo50 1:1,000 tiles. Please refer to the supplied tile layout shape file for specific details, naming conventions, etc.

Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is +/- 15 cm.

Index tiles for this dataset are available as layer Auckland 0.075m Urban Aerial Photos Index Tiles (2015-16)

This layer contains the DEM for LiDAR data from the Wellington region captured in 2013. Note that this DEM is based on automated point cloud classification and contains some residual remnants of surface features.

The DSM is available as layer Wellington LiDAR 1m DSM (2013).
The index tiles are available as layer Wellington LiDAR Index Tiles (2013).
The LAS point cloud is available from OpenTopography.

Lidar was captured for Greater Wellington Regional Council by Aerial Surveys in 2013. The datasets were generated by Landcare Research. The survey area includes Wellington, Porirua, Lower Hutt, Upper Hutt, Wairarapa, and Kapiti. Data management and distribution is by Land Information New Zealand.

Data comprises:
•DEM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout
•DSM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout
•Point cloud: las tiles in NZTM2000 projection, tiled into a 1km x 1km tile layout

Data was collected at >1 pulse/square metre pulse density. Attributes include:
-Elevation
-Intensity values
-Return number
-Adjusted GPS time
-Classification

Vertical datum is NZVD2016

This layer provides metadata about cadastral surveys along with reference points indicating the location of the survey.

A cadastral survey determines and describes the spatial extent (including boundaries) of interest of land within New Zealand. Each survey is allocated a unique reference number (that prior to Landonline included reference to the land district.

This data provides details that identify the type of survey, the purpose, description and key dates relating to the survey.
