Vertical Datums - NAVD 88 and EGM 96

Discussion created by GlennNead on Jul 27, 2012
I've seen references to converting NGVD 29 to NAVD 88 and from WGS84 ellipsoid to EGM96 geoid, but I do not see anything related to converting between NAVD 88 and EGM 96.  Are they synonymous?  If not, can you please point me in the right direction?
