Details for New Zealand Vertical NZGeoid05 Support

Name:New Zealand Vertical NZGeoid05 Support
Description:These tools provide support for New Zealand Vertical NZGeoid05.


These tools consist of a set of python scripts to convert between any of the 13 New Zealand MSL datums and NZGeoid05. They rely on an ArcGIS Desktop (Arcview level) license and access to a 3d Analyst license.

These tools use shapefiles and can be of either point, polyline or polygon type.

The NZGeoid05 model is available as an ascii grid for download at

Ensure the data is of the same spatial reference and in the extent of the model spatial extent.

I have also included a word document instruction guide and a sample NZGeoid05 vertical projection file. Support i9s for calculating both h and H,
