<p>The BLF55-NZVD2016 grid enables the conversion of normal-orthometric heights from the Bluff 1955 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016). </p>
<p>The conversion value is represented by the attribute “O”, in metres. </p>
<p>This conversion and NZVD2016 are formally defined in the LINZ standard <a href="http://www.linz.govt.nz/regulatory/25009">LINZS25009</a>. </p>
<p>BLF55-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Bluff 1955 vertical datum (168.2° E to 168.9° E, 46.3° S to 46.8° S). </p>
<p>The height conversion grid models the difference between the Bluff 1955 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of BLF55-NZVD2016 is better than 3 centimetres (95% Confidence interval). </p>
