Elevation or altitude is generally expressed as "metres above mean sea level" in the metric system, or "feet above mean sea level" in United States customary and imperial units. Common abbreviations in English are: AMSL – above mean sea level [3] ASL – above sea level [4] FAMSL – feet above mean sea level [5] FASL – feet above sea level [6]

In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height.

Sylmar gently slopes upward as a geological alluvial plain and alluvial fan from an elevation of slightly more than 1,100 feet (340 m) above sea level near San Fernando Road to slightly more than 1,700 feet (520 m) above sea level at the crest of Hubbard Street. The overall range of elevation in Sylmar is approximately 600 feet (180 m).
The orthometric height (symbol H) is the vertical distance along the plumb line from a point of interest to a reference surface known as the geoid, the vertical datum that approximates mean sea level. [1] [2] Orthometric height is one of the scientific formalizations of a layman's "height above sea level", along with other types of heights in ...
Tunnel datum is a datum based on an ordnance datum and used in designing tunnels which pass below sea level. for the London Underground, a tunnel datum of ODN −100 m is used; [7] thus a depth of −60 m AOD is 40 m ATD (above tunnel datum) for the Channel Tunnel, a tunnel datum of ODN −200 m is used; [8] thus a depth of −60 m is 140 m ATD
Driskill Mountain (also referred to as Mount Driskill) is the highest natural summit in Louisiana, with an elevation of 535 feet (163 m) above sea level. [3] It lies about 5.3 miles (8.5 km) southeast of Bryceland, in Bienville Parish. A large pile of rocks marks the high point.
The Ebright Azimuth is the point with the highest benchmark monument elevation in the U.S. state of Delaware. It is marked with a geodetic benchmark monument and has an elevation of 447.85 feet (136.50 m) above sea level. The only state high-point with a lower elevation is Britton Hill in the state of Florida at 345 feet (105 m) above sea level.
