The topographic elevation of a summit measures the height of the summit above a geodetic sea level. [1] [2] The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. [3] [2] The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of ...
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief , but also natural ...
Differences in roughness (topographic relief) result from a variety of processes acting on the underlying rock. The plate tectonic history of a region strongly influences the rock type and structure exposed at the surface, but differing rates of erosion that accompany changing climates can also have profound impacts on the land.

Interfluve – Land between two converging, or confluent, rivers; Inverted relief – Landscape features that have reversed their elevation relative to other features; Island – Piece of subcontinental land surrounded by water; Islet – Very small island; Isthmus – Narrow strip of land connecting two larger land areas
[3] [4] The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. [5] [4] The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. [6] In greater North America, only Denali exceeds 6000 meters (19,685 feet) elevation ...

The term "United States," when used in the geographic sense, refers to the contiguous United States (sometimes referred to as the Lower 48, including the District of Columbia not as a state), Alaska, Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, American Samoa, and minor outlying possessions.

All topographic elevations are adjusted to the North American Vertical Datum of 1988 (NAVD 88). All geographic coordinates are adjusted to the World Geodetic System of 1984 (WGS 84) . The mean elevation for each state, the District of Columbia, and Puerto Rico are accurate to the nearest 100 feet (30 m).
