Northland Region Data

This layer contains the DEM for LiDAR data in the northern Auckland Region captured between 2016 and 2018.

• The DSM is available as layer Auckland North LiDAR 1m DSM (2016-2018).

• The index tiles are available as layer Auckland North LiDAR Index Tiles (2016-2018).

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

LiDAR was captured for Auckland Council by Aerial Surveys from 16 August 2016 to 9 August 2018. These datasets were generated by Aerial Surveys and their subcontractors. Data management and distribution is by Toitū Te Whenua 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 specification is at a minimum of 4 pulses/square metre.

Vertical Accuracy Specification is +/- 0.2m (95%).

Horizontal Accuracy Specification is +/- 0.6m (95%).

Vertical datum is NZVD2016.

Orthophotography in the Northland Region taken in 2016. Coverage is of urban areas with the Far North, Kaipara, and Whangarei District Council areas.

Imagery was captured for the ‘Northland Aerial Imagery Consortium (NAIC)’ by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.

Data comprises:
• 3,289 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:500 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 1:500 tiles. Please refer to the tile index layer for specific details, naming conventions, etc.

Imagery supplied as 10cm pixel resolution (0.1m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15m @ 68% confidence level in clear open spaces (1 sigma) over area of interest.

Index tiles for this dataset are available as layer Northland 0.1m Urban Aerial Photos Index Tiles (2016)

Index Tiles ONLY, for actual orthophotos see layer Northland 0.1m Urban Aerial Photos (2016)
