This layer is a component of the Topo500 data. The Topo500 map series will, when it is created, provide updated topographic mapping for the New Zealand mainland at 1:500,000 scale.

This layer contains the Index Tiles for LiDAR data in the Northland Region surronding Whangarei Heads captured in 2016.

• The DEM is available as layer Northland - Whangarei Heads LiDAR 1m DEM (2016).

• The DSM is available as layer Northland - Whangarei Heads LiDAR 1m DSM (2016).

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

LiDAR was captured for Toitū Te Whenua Land Information New Zealand by Aerial Surveys in November 2016. 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 2 pulses/square metre.

Vertical datum is NZVD2016.
