Does WGS84 LatLon coordinates and EGM96 LatLon coordinates are the same?
Is difference for [Lat;Lon;Ele] is in elevation only?
If I have, for example, a [Lat;Lon] point in WGS84, I can take elevation from NASADEM_HGT.001 dataset (which is in EGM96) without any conversion of Lat\Lon and this will be accurate elevation for this point in EGM96. By adding calculated undulation for [Lat;Lon], I can find WGS84 Elevation.
Am I correct ?
How can I 'proof' that to myself? Any docs?
