Explanation:
Height above mean sea level
Explanation:
Height above mean sea level is a term for expressing the elevation or altitude of an object compared to the average sea level data.
Mean sea level (MSL) is the average of the surface levels of one or more of Earth's water bodies.
Sea levels can be affected by many factors due to various geological factors. 20th century and the present millennium is affected due to global warming.
AMSL data is required to measure the height of a hill station, the altitude of a flight, study climate change, atmospheric science, land survey, etc.
The elevation of a mountain denotes the highest point of that mount above mean sea level and it is measured using difference in atmospheric pressures.
It is very rare for a location to be below sea level and have negative AMSL. One such example is the Amsterdam Airport Schiphol.
