Elevation (The height of a fixed position above sea level) Example: Denver, Colorado in the United States is 5,183 ft. above sea level. 1  Find The Elevation Of Most Any U.S City.  Find the high and low points in any country.
The term above mean sea level (AMSL) is the elevation or altitude of any object, relative to the average sea level.For example, an ocean beach would be at 0 AMSL. AMSL is used in radio (both in broadcasting and other telecommunications uses) by engineers to determine the coverage area a station will be able to reach.he sea level also changes over time when measured in the same place. The sea moves, high and low pressure zones affect the height, tides change the sea level, and local difference in gravity all affect the sea level. People can only pick a spot and calculate the mean sea level at that point and use it as a datum.
