How is elevation measured?
Elevation is the height above mean sea level. In the US the official reference is the NAVD88 vertical datum. Summits are surveyed on the ground, with leveling and precise GPS. The USGS 3DEP is an elevation model of the whole country, largely from 1-meter lidar: it gives the ground height at every point. That’s why it can differ by a few feet from the official figure of a sharp summit.
