Tasman District Layers

This layer contains the DSM for LiDAR data from Golden Bay - Aorere Extension, Lee Dam, St Arnaud and Farewell Spit captured in 2017.

• The DEM is available as layer Tasman - Golden Bay LiDAR 1m DEM (2017).

• The index tiles are available as layer Tasman - Golden Bay LiDAR Index Tiles (2017).

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

Lidar was captured for Tasman District Council by AAM New Zealand in November and December 2017. The datasets were generated by AAM New Zealand 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, Farewell Spit tiled into a 1:1,000 tile layout, the rest of the data tiled into a 1:2,000 tile layout

Pulse density specification is 2 pulses/square metre.

Vertical accuracy specification is +/- 0.12m (95%).

Horizontal accuracy specification is +/- 1.00m (95%).

Vertical datum is NZVD2016.
