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

• The DEM is available as layer Auckland North LiDAR 1m DEM (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.
