What is above mean sea level (AMSL)?
Height above mean sea level is a measure of a location's vertical distance ( height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.

The term above sea level generally refers to above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator.
The term above mean sea level (AMSL) is the elevation or altitude used by engineers to determine the coverage area a station will be able to reach. It is also used in aviation , where most heights are recorded and reported in AMSL (see flight level ), and in the atmospheric sciences .
The sea level is the average height of the ocean (informally called the sea ). The word 'average' must be used because the height of the sea changes with the tides. The height of mountains, countries, and so on, is almost always given as "above sea level".
[1] [2] Orthometric height is one of the scientific formalizations of a laypersons' "height above sea level", along with other types of heights in Geodesy . In the US, the current NAVD88 datum is tied to a defined elevation at one point rather than to any location's exact mean sea level.
Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.
Mean high water neaps (MHWN) – The average of the two high tides on the days of neap tides. Mean sea level (MSL) – This is the average sea level. The MSL is constant for any location over a long period. Mean low water neaps (MLWN) – The average of the two low tides on the days of neap tides.
