The AUK46-NZGD2000 grid enables the conversion of normal-orthometric heights from the Auckland 1946 local vertical datum directly to New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights.

AUK46-NZGD2000 is published on a one arc-minute grid (approximately 1.8 kilometres) extending over the benchmarks that nominally define the extent of the Auckland 1946 vertical datum (174.0° E to 176.2° E, 36.1° S to 38.0° S).

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

This grid is a combination of New Zealand Quasigeoid 2016 NZGeoid2016 and the AUK46-NZVD2016 height conversion grid. Where NZGeoid2016 is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016), while the AUK46-NZVD2016 grid models the difference between the Auckland 1946 vertical datum and NZVD2016 using the LINZ GPS-levelling marks.

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

The AUK46-NZVD2016 grid enables the conversion of normal-orthometric heights from the Auckland 1946 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.

AUK46-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Auckland 1946 vertical datum (174.0° E to 176.2° E, 36.1° S to 38.0° S).

The height conversion grid models the difference between the Auckland 1946 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of AUK46-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 DEM for LiDAR data from the Auckland region captured in 2013.
The DSM is available as layer Auckland Lidar 1m DSM (2013).
The index tiles are available as layer Auckland Lidar Index Tiles (2013).
The LAS point cloud and vendor project reports are available from OpenTopography.

Lidar was captured for Auckland Council by NZ Aerial Mapping & Aerial Surveying Limited. The capture of the data commenced on 17th July and was completed by the 23 November 2013. The datasets were generated by both ASL and NZAM. All raw point cloud data was produced by NZAM & ASL prior to data being sent to Genesys International for the data classification and product generation. The survey area includes the Auckland city urban area and adjacent rural land covering approximately 2250 square kilometers. Data management and distribution external to Auckland Council is managed by Land Information New Zealand.

Data comprises:
•DEM: 6423 asc files in NZTM projection, tiled into a 1:1,000 tile layout
•DSM: 6423 asc files in NZTM projection, tiled into a 1:1,000 tile layout
•Point cloud: 8224 las files in NZTM projection, tiled into a 1:1,000 tile layout

Data was collected at > 1.5 point/square metre point density. Attributes include:
-Elevation
-Intensity values
-Return number
-Adjusted GPS time
-Classification

Vertical accuracy specification is +/-0.2m (@ 95% confidence)
Horizontal accuracy specification is +/-0.6m (@ 95% confidence)

Verical Datum is NZVD2009
