When relief is described underwater, the term bathymetry is used. In cartography, many different techniques are used to describe relief, including contour lines and triangulated irregular networks. Elementary landforms (segments, facets, relief units) are the smallest homogeneous divisions of the land surface, at the given scale/resolution.
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 ...
Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution.
Interfluve – Land between two converging, or confluent, rivers, mainly in the Punjab; 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
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 information systems and geovisualization.
The Winnebago Tribe of Nebraska will soon get back about 1,600 acres (647 hectares) of land the federal government took more than 50 years ago and never developed. A new law will require the U.S ...
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.
The slope of the shelf is usually quite low, on the order of 0.5°; vertical relief is also minimal, at less than 20 m (66 ft). [ 17 ] Though the continental shelf is treated as a physiographic province of the ocean , it is not part of the deep ocean basin proper, but the flooded margins of the continent. [ 18 ]
