What Is Mean Sea Level Elevation

Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to the average sea level datum. The alternative is to use a geoid-based vertical datum such as NAVD Metres above sea level - Sea level - Sea level rise - Sea level equation. Metres above mean sea level (MAMSL) or simply metres above sea level (MASL or m a.s.l.) is a standard metric measurement in metres of vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level .

So that the surface of the ocean can be used as a base for measuring elevations, the concept of "local mean sea level" has been developed. Definition.

ELEVATION is the height of a point above (or below) sea level. SEA LEVEL or, as it is more usually called, mean sea level, is the average height of the surface of the sea.
