Historic Coordinate & Height Orders

Prior to May 2010 a different set of Orders was used to describe the accuracy of NZGD2000 and RSRGD2000 coordinates and normal-orthometric heights.

NZGD1949 coordinates also had its own unique Order system.

 

Historic Coordinate Orders

Prior to May 2010, the accuracy of NZGD2000 and RSRGD2000 coordinates was represented by a unique hierarchy of Orders that came into effect with the creation of the datums in 2000. more...

 

Historic Height Orders

Prior to May 2010 normal-orthometric heights in terms of the 13 mean sea level vertical datums were classified into five Orders according to the way that they were observed. more...

 

NZGD1949 Orders

NZGD1949 is a horizontal datum so only provides two-dimensional coordinates (latitude and longitude). The accuracy of the coordinates is described in terms of horizontal Orders based on the type of observations that were used. more...

 

NZGD1949 D coordinates

NZGD1949 D coordinates are coordinates that were computed and adjusted in terms of NZGD2000 and then transformed into NZGD1949 using the grid transformation. more...
