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
