For other uses of the word, see Elevation Elevation has several related meanings: Geography The elevation of a geographic location is its height above mean sea level (or possibly some other fixed point). ...
In geography, the elevation of a geographiclocation is its height above mean sea level (or possibly some other fixed point). The elevation of a mountain usually refers to its summit. A topographic map shows variations in elevation by contour lines. Elevation is mainly used when referring to points on the Earth itself, while altitude is used for points in the air, such as an aircraft.

Geography is a synthetic science, dependent for the data with which it deals on the results of specialized sciences such as astronomy, geology, oceanography, meteorology, biology and anthropology, as well as on topographical description.
General geography was divided into - (I) the Absolute part, dealing with the form, dimensions, position and substance of the earth, the distribution of land and water, mountains, woods and deserts, hydrography (including all the waters of the earth) and the atmosphere; (2) the Relative part, including the celestial properties, i.e.
Kant's lectures on physical geography were delivered in the university of Konigsberg from 1765 onwards.' Geography appealed to him as a valuable educational discipline, the joint foundation with anthropology of that " knowledge of the world " which was the result of reason and experience.
Included on most nautical charts are depths of water, characteristics of the bottom, elevations of selected topographic features, general configurations and characteristics of the coast, the shoreline (usually the mean high water line), dangers, obstructions and aids to navigation limited tidal data, and information about magnetic variation in the charted area.
Region of uniform general slope, comparatively level, of considerable extent, and not broken by marked elevations and depressions (it may be an extensive valley floor or a plateau summit); an extent of level or nearly level land; a flat, gently sloping, or nearly level region of the sea floor.
Surveying instrument designed for use in the rapid determination of distance, direction, and difference of elevation from a single observation, using a short base which may be an intergraph part of the instrument.
