Altimeter, that measures atmospheric pressure, which decreases as altitude increases.A geoid is needed to convert the 3D position to sea-level elevation. Global Navigation Satellite System (like GPS), where a receiver determines a location from pseudoranges to multiple satellites.The elevation or altitude in metres above sea level of a location, object, or point can be determined in a number of ways. Flying objects such as airplanes or helicopters.The top of buildings and other structures.Geographic locations such as towns, mountains and other landmarks.Metres above sea level is the standard measurement of the elevation or altitude of: For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Mean sea levels are affected by climate change and other factors and change over time. 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". In geodesy, it is formalized as orthometric heights. 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.

Everest or Chimborazo is at the higher elevation, as the Chimborazo summit is further from the Earth's center, while the Mt. Due to equatorial bulge, there is debate as to which of the summits of Mt. Less commonly, elevation is measured using the center of the Earth as the reference point. The resolution of the gridded data varies from true 2-minute for the Atlantic, Pacific, and Indian Ocean floors and all land masses to 5 minutes for the Arctic Ocean floor. A Mercator projection was used for the world image, which spans 390° of longitude from 270° West around the world eastward to 120° East latitude coverage is ☘0°. Assumed illumination is from the west shading is computed as a function of the east-west slope of the surface with a nonlinear exaggeration favoring low-relief areas. This image was generated by NOAA from digital data bases of land and sea-floor elevations on a 2-minute latitude/longitude grid (1 minute of latitude = 1 nautical mile, or 1.853 km). Elevation, or geometric height, 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. 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 (see Geodetic system, vertical datum).
