The DBL60-NZVD2016 grid enables the conversion of normal-orthometric heights from the Dunedin-Bluff 1960 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016).

The conversion value is represented by the attribute “O”, in metres.

This conversion and NZVD2016 are formally defined in the LINZ standard LINZS25009.
DBL60-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Dunedin-Bluff 1960 vertical datum (167.4° E to 169.9° E, 45.0° S to 46.7° S).

The height conversion grid models the difference between the Dunedin-Bluff 1960 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of DBL60-NZVD2016 is better than 2 centimetres (95% Confidence interval).

More information on converting heights between vertical datums can be found on the LINZ website.

This layer contains the Index Tiles for LiDAR data from the Queenstown Area of the Otago Region captured in 2016.

Lidar was captured for Otago Regional Council by Aerial Surveys in March and April 2016. The 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 is 2 pulses/square metre.

Vertical accuracy specification is +/- 0.044m (95%).

Vertical datum is NZVD2016.
