A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area. Differences in hypsometric curves between landscapes arise because the geomorphic processes that shape the landscape may be different.
Hypsometric is a scientific term relating to the measurement of heights. The term originates from the Greek word ὕψος "hypsos" meaning height and the word metre is from the Greek μέτρον (métron), "a measure". Hypsometric curve is a histogram of elevations of a landscape; Hypsometric equation relates pressure to height in the atmosphere
The historical bathymetric map shown at the right is an example of discrete hypsometric tinting. In a map with continuous hypsometric tinting, there is a gradual shift from one tint to another, which presents a smoother appearance. This is often accomplished using data from a digital elevation model (DEM).
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.
Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography , and as such its portrayal presents a central problem in cartographic design , and more recently geographic ...
A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. [4] The contour interval of a contour map is the difference in elevation between successive contour lines. [5] The gradient of the function is always perpendicular to the contour ...
A seafloor map captured by NASA Bathymetry ( / b ə ˈ θ ɪ m ə t r i / ; from Ancient Greek βαθύς ( bathús ) 'deep' and μέτρον ( métron ) 'measure') [ 1 ] [ 2 ] is the study of underwater depth of ocean floors ( seabed topography ), lake floors, or river floors.
A simple scale hypsometer allows the height of a building or tree to be measured by sighting across a ruler to the base and top of the object being measured, when the distance from the object to the observer is known.
