A contour line (also isoline, isopleth, isoquant or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. [ 1][ 2] It is a plane section of the three-dimensional graph of the function parallel to the -plane. More generally, a contour line for a function ...
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. Traditional definitions require a topographic map to show both ...
Terrain cartography. USGS topographic map of Stowe, Vermont with contour lines at 20-foot intervals. 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 ...
Topographic profile. A topographic profile or topographic cut or elevation profile is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level. [ 1]
Web mapping has also uncovered the potential of crowdsourcing geodata in projects like OpenStreetMap, which is a collaborative project to create a free editable map of the world. These mashup projects have been proven to provide a high level of value and benefit to end users outside that possible through traditional geographic information.
This page provide conventions to produce topographic maps. Topographic maps, displaying an area's relief, de facto explain many other things such as human occupation, cultivated areas, kingdoms borders, exchanges ways, etc. If you create a topographic map, note that these colorimetric values are indicatives.
First map of oceanic bathymetry, derived from USS Dolphin (1836) data. In the 18th century, spot heights were first interpolated to create contour lines. In the late 1820s, Franz von Hauslab was credited for the first colored contour maps using lithography. With the invention of chromolithography, copies of colored maps became more accessible.
