Bluff 1955 to NZGD2000 Conversion
The BLF55-NZGD2000 grid enables the conversion of normal-orthometric heights from the Bluff 1955 local vertical datum directly to New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights.
BLF55-NZGD2000 is published on a one arc-minute grid (approximately 1.8 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).
The conversion value is represented by the attribute “delta”, in metres.
This grid is a combination of New Zealand Quasigeoid 2016 [NZGeoid2016]( https://data.linz.govt.nz/layer/3418 ) and the [BLF55-NZVD2016]( https://data.linz.govt.nz/layer/3424 ) height conversion grid. Where NZGeoid2016 is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016), while the BLF55-NZVD2016 grid models the difference between the Bluff 1955 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]( http://www.linz.govt.nz/data/geodetic-services/coordinate-conversion/converting-between-nzvd2016-nzgd2000-and-local-vertical-datums ).
