NZGD2000 Deformation Model
NZGD2000 is a three-dimensional semi-dynamic datum. A semi-dynamic datum uses a deformation model to correct coordinates and survey observations for the effect of regional-scale tectonic movements of the Earth's crust. The model causes all coordinates and observations to be stored as if they were observed at the same time or reference epoch, which in the case of NZGD2000 is 1 January 2000.
