Vertical Datum 2016 Data - Page 3

The Stewart Island 1977 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 Stewart Island 1977 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 Stewart Island 1977 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).

This index enables users to identify the extent of the relationship grids provided on LDS, which are used to convert heights provided in terms of one of 13 historic local vertical datums to NZVD2016.

The polygons comprising the index show the extent of the conversion grids.

Users can view the following polygon attributes:
Shape_VDR: Vertical Datum Relationship grid area
LVD: Local Vertical Datum
Control: Number of control marks used to compute the relationship grid
Mean: Mean vertical datum relationship value at control points
Std: Standard deviation of vertical datum relationship value at control points
Min: Minimum vertical datum relationship value at control points
Max: Maximum vertical datum relationship value at control points
Range: Range of vertical datum relationship value at control points
Ref: Reference control mark for the local vertical datum
Ref_value: Vertical datum relationship value at the reference mark
Grid: Formal grid id

Users should note that the values represented in this dataset have been calculated with the outliers excluded. These same outliers were excluded during the computation of the relationship grids, but were included when calculating the 95% confidence intervals
