Hi,

I have a network of sites in New Zealand and I'd like to know their elevation above mean sea level using the Calculate Geometry tool.  Which is the best Z coordinate system to use?  Do I need to find localised geoid heights for each site to calculate the orthometric heights accurately?  Will these reults be more accurate than google earth?

Cheers, Josh
