Dunedin City Data

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.

This layer provides the current strata parcel polygons and their associated descriptive data as a single layer to facilitate their use independently of other primary parcels or non primary parcels.

Strata parcels are portions of land where the vertical extent is limited.

The combination of this layer with the primary parcels layer provides all current parcels for New Zealand (i.e. excludes Historic and Pending parcels)

If you require approved or historic parcels see the All Parcels Layer

This layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the Survey Boundary Marks layer which contains accuracies for each parcel node.

The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. For more information see

This layer contains the DEM for LiDAR data from the Otago Region captured in 2016.

• The DSM is available as layer Otago LiDAR 1m DSM (2016).

• The index tiles are available as layer Otago LiDAR Index Tiles (2016).

• The LAS point cloud and vendor project reports are available from OpenTopography.

Lidar was captured for Otago Regional Council by Aerial Surveys in March and April 2016. The datasets were generated by Aerial Surveys and their subcontractors. 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 1:1,000 tile layout

Pulse density is 2 pulses/square metre.

Refer to individual survey reports for accuracy statistics.

Vertical datum is NZVD2016.
