The NZ Elevation Survey Index dataset provides an index to all LiDAR derived elevation datasets found on the LINZ Data Service. Each record in the dataset provides both a geometry of the extent of the elevation survey, as well as useful metadata attributes. The extents are derived from the maximum extent of DEM and DSM coverage and consist of full NZTopo50 1k tiles, even where a tile is only partially covered with data. These extents only provide a rough indication of corresponding point cloud coverage which can be quite different for some elevation surveys.

Please refer to the NZ Aerial Surveys Data Dictionary for detailed metadata and information about this dataset.

The elevation data referenced by this dataset is available on the LINZ Data Service.

This layer contains the DEM for LiDAR data in the West Coast Region of Westport and surrounding area captured in June 2020.

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

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

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

LiDAR was captured for West Coast Regional Council by Aerial Surveys on 22 and 30 June 2020. These datasets were generated by Aerial Surveys and their subcontractors. Data management and distribution is by Toitū Te Whenua Land Information New Zealand. Co-funding was provided by the Ministry of Business, Innovation and Employment Provincial Development Unit.

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.
