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 DEM for LiDAR data in the Waikato Region surronding Huntly, Port Waikato and other small areas captured between 2015 and 2019.

• The DSM is available as layer Waikato - Huntly LiDAR 1m DSM (2015-2019).

• The index tiles are available as layer Waikato - Huntly LiDAR Index Tiles (2016).

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

LiDAR was captured for Waikato Regional Council by Aerial Surveys from 8 February 2015 to 24 January 2019. 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 datum is NZVD2016.
