This layer contains the DSM for LiDAR data in the Marlborough Region covering the Flaxbourne River, Lake Grassmere, Seddon, Lower Awatere Valley, Picton, Waikawa, the Wairau Valley and Plains, including Spring Creek, Tuamarina and parts of Blenheim in 2018.

LiDAR was captured for Marlborough District Council by Aerial Surveys between May and September 2018. 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 3.5 pulses/square metre.

Vertical accuracy specification is +/- 0.2m (95%).

Horizontal accuracy specification is +/- 1.0m (95%)

Vertical datum is NZVD2016.

This dataset was first added to LINZ Data Service on 07 Oct 2019.

The Nelson 1955 to NZVD2016 Conversion Raster provides users with a two arc-minute (approximately 3.6 kilometres) raster image of the conversion of normal-orthometric heights from the Nelson 1955 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.

The height conversion grid models the difference between the Nelson 1955 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy is better than 2 centimetres (95% Confidence interval).

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