The elevation of a geographic location is its height above a fixed reference point, often the mean sea level. Geography (from Greek γεωγραφία - geografia) is the study of the Earth and its lands features inhabitants and phenomena In Geography, location is a position or point in Physical space that something occupies on Earths' surface The term above mean sea level ( AMSL) refers to the Elevation (on the ground or Altitude (in the Air) of any object relative to the 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. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 Altitude is the Elevation of a point or object from a known level or datum (plural data Geopotential height is a vertical coordinate referenced to Earth's Mean sea level — an adjustment to geometric height ( Elevation above mean sea level using the A spacecraft is a Vehicle or machine designed for Spaceflight.

Less commonly, elevation is measured using the center of the Earth as the reference point. Due to equatorial bulge, there is debate whether the summits of Mt. Everest or Chimborazo are at the higher elevation, as the Chimborazo summit is further from the Earth's center while the Mt. An equatorial bulge is a bulge which a planet may have around its Equator, distorting it into an Oblate spheroid. Mount Everest, also called Sagarmatha (सगरमाथा meaning Head of the Sky) or Chomolungma, Qomolangma or Zhumulangma (in The inactive Stratovolcano Chimborazo (tʃimboˈraso is Ecuador's highest summit Everest summit is higher above mean sea level.

Maps and GIS

A topographical map is the main type of map used to depict elevation, often through use of contour lines. A topographic map is a type of Map characterized by large-scale detail and quantitative representation of relief, usually using Contour lines in modern A map is a visual representation of an area—a symbolic depiction highlighting relationships between elements of that space such as objects, Regions, and Themes A contour line (also Level set, isopleth, isoline, isogram or isarithm) of a function of two

In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. A digital elevation model ( DEM) is a Digital representation of ground Surface Topography or Terrain. Digital terrain models are another way to represent terrain in GIS. A digital elevation model ( DEM) is a Digital representation of ground Surface Topography or Terrain.

To determine elevation of a place, it must be surveyed, in reference to a ground control point. Geophysical survey refers to the systematic collection of geophysical data for spatial studies

Topography

The elevation of a mountain usually refers to its summit. A mountain is a Landform that extends above the surrounding Terrain in a limited area with a peak In topography a summit is a point on a surface which is higher in Elevation than all points immediately adjacent to The elevation of a hill also refers to the summit. A valley's elevation is usually taken from the lowest point but is often taken all over the valley.
