Conversion from EGM96 to NAVD88 Can you please let me know or confirm that once we do a conversion from EGM96 to NAVD88, elevations for EGM96 should be higher than NAVD88? and if you can tell me by how much? I found differ...

Prepare your data for the National Spatial Reference System modernization of 2022 in the U.S. (ArcGIS Blog) The new U.S. datums of 2022 will soon be released. This article covers what is coming and how you should prepare your data.

Prepare for #NSRS
#NGS will replace all 3 current North American Datum of 1983 #NAD83 frames and all current vertical datums, including the North American Vertical Datum of 1988 #NAVD88, with four new terrestrial reference frames and a vertical geopotential datum.
