- From Simple English Wikipedia, the free encyclopedia 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 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. Definition. A "mean sea level" is imaginary.
Height above mean sea level is a measure of the vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level".
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. It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (MSL) (contrast with flight level ), and in the atmospheric sciences , and land surveying .

The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The term elevation is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Elevation is not to be
In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is 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.
GIS or geographic information system is a computer system that allows for visualizing, manipulating, capturing, and storage of data with associated attributes. GIS offers better understanding of patterns and relationships of the landscape at different scales. Tools inside the GIS allow for manipulation of data for spatial analysis or cartography.

This map is derived from GTOPO30 data that describes the elevation of Earth's terrain at intervals of 30 arcseconds. It uses hypsometric tints instead of contour lines to indicate elevation.
Frae Wikipedia, the free beuk o knawledge (Reguidit frae Above mean sea level) Mean sea level (MSL) is a datum representin the average hicht o the ocean 's surface (like hauf the wey atween the mean heich tide an the mean law tide); uised as a staundart in reckonin land elevation.
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. At high altitude, atmospheric pressure is lower than that at sea level.
The aneroid altimeter is calibrated to show the pressure directly as an altitude above mean sea level, in accordance with a mathematical model atmosphere defined by the International Standard Atmosphere (ISA). Older aircraft used a simple aneroid barometer where the needle made less than one revolution around the face from zero to full scale.
