• NZGD2000: A semi-dynamic datum

  New Zealand Geodetic Datum (NZGD2000) is a semi-dynamic datum. This means that the effects of plate tectonics are considered as part of the processes and frameworks when determining a coordinate for a position. However, the impact might not be immediately…

• Normal-orthometric heights

  There are 2 main height systems used in New Zealand, with normal-orthometric being the most common. This takes into account the quasigeoid and the influence of gravity to support accurate elevation measurements.

• Extra protection for permanent reference marks (PRMs)

  Important survey marks can be disturbed, damaged or destroyed simply because people are unaware of them. Marks below ground level are most at risk as they are practically invisible to those working nearby.
