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.
Topographic maps conventionally show topography, or land contours, by means of contour lines. Contour lines are curves that connect contiguous points of the same altitude . In other words, every point on the marked line of 100 m elevation is 100 m above mean sea level.
Located within the White Mountains of Arizona and surrounded by the Apache-Sitgreaves National Forest Greer is the highest town in the state at an elevation of approximately 8,400 feet (2,600 m). The highest incorporated town in Arizona is Eagar at an elevation of 7,080 feet (2,160 m). Eagar lies 20 minutes northeast of Greer along the New ...
The elevation of a geographic area may be stated in several ways. These include: The maximum elevation of the area (high point); [a] The minimum elevation of the area (low point); [b] The arithmetic mean elevation of the area (statistical mean elevation); [c] The median elevation of the area (statistical 50% elevation); [d] and; The elevation ...
To be included on the list, a place needs to be an incorporated municipality (i.e. a city, town, or village) and it needs to be at an elevation of 3,000 feet (914 m) or higher. In the United States, settlements above 3,000 feet are found primarily on the High Plains , in the Rocky Mountains , and in Western North Carolina .
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]

In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often 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.
