Extract Multi Values to Points - EGM2008

Y_Chau

I get ellipsoidal heights in feature geometries from Field Maps. We have this tool in ArcGIS Pro - Extract Multi Values to Points. Where can I get a EGM2008 surface to extract geoid separation for each point using this tool? Then I will be able to calculate geoid heights.

Thanks

I am not sure can you really get a surface to calculate difference, but this will help in topic generally:

By adding this additonal installer you can easily convert ellipsoidal heights to EGM2008 in ArcGIS Pro
