The following is a list of the world's major cities (either capitals, more than one million inhabitants or an elevation of over 1,000 m [3,300 ft]) by elevation. In addition, the country, continental region, latitude and longitude are shown for all cities listed.
Using the title of a settlement can be misleading in the absence of any widely accepted definition. For example, city status in the United Kingdom historically arose from its place in the ecclesiastic hierarchy. (In modern times, city status is awarded for secular reasons but without reference to size.)
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.
The city is closest to Ebright Azimuth, the highest point in the state 409 feet (125 m) Washington DC District of Columbia [11] Fort Reno Park has the highest point in the District of Columbia. [11] 345 feet (105 m) Lakewood Florida [12] Unincorporated settlement by Britton Hill, the highest natural point in Florida. Britton Hill is the lowest ...
Also datum level or datum line. The zero-elevation baseline or vertical datum to which a measurement of elevation or altitude is relative, e.g. the mean sea level calculated for a given location over a given period of time. [4] See also geodetic datum. de facto segregation The spatial and social separation of populations that occurs without ...
The length of full hematological adaptation can be approximated by multiplying the altitude in kilometres by 11.4 days. For example, to adapt to 4,000 metres (13,000 ft) of altitude would require 45.6 days. [27] The upper altitude limit of this linear relationship has not been fully established. [6] [16]
Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or AGL) as the reference datum. Pressure altitude divided by 100 feet (30 m) is the flight level , and is used above the transition altitude (18,000 feet (5,500 m) in the US, but may be as low as 3,000 feet (910 m) in other jurisdictions).
The digital elevation model (DEM) is a raster-based digital dataset of the topography (hypsometry and/or bathymetry) of all or part of the Earth (or a telluric planet). The pixels of the dataset are each assigned an elevation value, and a header portion of the dataset defines the area of coverage, the units each pixel covers, and the units of ...
