Question

height above sea level is called​

Answer 1

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.

Answer 2

The height above sea level is called elevation.

• Sea level is known as the base level used in the measurement of depth and elevation on earth.
• It is possible to use this level of measurement because the sea is a continuous body of water.
• So, its surface is considered to be of the same level all over the world.
• Hence, elevation is the vertical distance of a point measured from the sea level.
• The vertical distance can be of a point either above or below sea level.
