Westland District Data

This layer contains the DSM for LiDAR data in the West Coast Region, captured between 2020 and 2022.

• The DEM is available as layer West Coast LiDAR 1m DEM (2020-2022).

• The index tiles are available as layer West Coast LiDAR Index Tiles (2020-2022).

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

LiDAR was captured for West Coast Regional Council by Aerial Surveys between 16 May 2020 and 14 February 2022. These 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 specification is at a minimum of 4 pulses/square metre.

Vertical Accuracy Specification is +/- 0.2m (95%)
Horizontal Accuracy Specification is +/- 1.0m (95%)

Vertical datum is NZVD2016.
