Maximum elevation figure (MEF) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area. It is of interest to pilots, who want to be aware of the highest mountain peaks and tall towers nearby, so that they can fly above them to avoid controlled flight into ...
Hypsometry (from Ancient Greek ὕψος (húpsos) 'height' and μέτρον (métron) 'measure') [1] [2] is the measurement of the elevation and depth of features of Earth's surface relative to mean sea level. [3] On Earth, the elevations can take on either positive or negative (below sea level) values.
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 ...
A plot of geopotential height for a single pressure level in the atmosphere shows the troughs and ridges (highs and lows) which are typically seen on upper air charts. The geopotential thickness between pressure levels – difference of the 850 hPa and 1000 hPa geopotential heights for example – is proportional to mean virtual temperature in ...
The true elevation is between that shown and the elevation plus forty feet since the relevant topographic maps all use 40-foot contours. Boundary Peak is the highest peak in terms of elevation, however, it has only 253 feet of clean prominence and so is usually considered a subsidiary peak of Montgomery Peak in California.

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 ...
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.
